Answer: Option 2 — 2 only

Only statement 2 is correct. The position of Leader of the Opposition in the Lok Sabha was formally recognized for the first time in 1969. The other two statements contain factual errors regarding the largest opposition party in the first Lok Sabha and the minimum strength required for recognition as Leader of the Opposition.

❌ Statement 1 – Incorrect: In the first Lok Sabha (1952), the single largest opposition party was the Communist Party of India (CPI) with 16 seats, not the Swatantra Party (which was formed only in 1959).

✅ Statement 2 – Correct: The Leader of the Opposition in the Lok Sabha was formally recognized for the first time in 1969 when the post was accorded statutory recognition under the Salary and Allowances of Leaders of Opposition in Parliament Act, 1977 (with retrospective effect from 1969).

❌ Statement 3 – Incorrect: The minimum requirement for recognition as Leader of the Opposition is not 75 members but 10% of the total strength of the House, which amounts to 55 members (10% of 545) in the current Lok Sabha.

📝 Short Notes: Leader of the Opposition

• Statutory Recognition: The post of Leader of the Opposition was given statutory recognition through the Salary and Allowances of Leaders of Opposition in Parliament Act, 1977.
• First Recognition (Lok Sabha): Ram Subhag Singh of Congress (O) was the first formally recognized Leader of the Opposition in 1969.

Answer: Option 3 — 1 only

The value of the vote of each MLA varies from State to State because it is calculated based on the population of the state divided by the number of elected MLAs in that state. However, all MPs (both Lok Sabha and Rajya Sabha) have equal voting value in Presidential elections, making Statement 2 incorrect.

✅ Statement 1 – Correct: The value of an MLA's vote is calculated as (Population of State ÷ Number of MLAs ÷ 1000), which varies across states based on population and assembly strength.

❌ Statement 2 – Incorrect: All MPs have equal voting value in Presidential elections; the value is the same for both Lok Sabha and Rajya Sabha members.

Detailed Explanation:

Answer: Option 2 — If there are no laws, there is no liberty.

This statement reflects the most appropriate relationship between law and liberty. Liberty does not mean absolute freedom but freedom within the framework of law. Without laws, society would descend into anarchy where the strong would dominate the weak, and individual rights would have no protection. Laws provide the structure that protects individual freedoms, ensures equality, and prevents one person's liberty from infringing upon another's. True liberty exists only when it is regulated and protected by law.

❌ Option 1 – Incorrect: More laws do not necessarily mean less liberty; well-designed laws actually protect and enhance liberty by preventing exploitation and ensuring justice.

✅ Option 2 – Correct: Laws are the foundation of liberty, providing the framework within which freedom can be exercised without descending into chaos.

❌ Option 3 – Incorrect: While democratic participation in law-making is important, liberty can exist even when laws are made through representative mechanisms rather than directly by all people.

❌ Option 4 – Incorrect: Frequent changes in laws do not inherently endanger liberty; what matters is the substance and purpose of laws, not their frequency of change.

📝 Short Notes: Law and Liberty

• Complementary Relationship: Law and liberty are not opposed but complementary; law creates the conditions for liberty to flourish.
• Rule of Law: The principle of Rule of Law ensures that liberty is protected through legal frameworks that apply equally to all citizens.
• Negative vs Positive Liberty: Laws prevent negative liberty (freedom from interference) from becoming license, and enable positive liberty (freedom to achieve potential).
• Constitutional Safeguards: Constitutional provisions and fundamental rights define the scope of liberty while laws provide mechanisms for their enforcement.
• Social Contract Theory: Thinkers like Hobbes, Locke, and Rousseau emphasized that individuals surrender certain freedoms to the state in exchange for protection of their remaining liberties through law.
• Balance: The challenge is to ensure laws are just and proportionate, protecting liberty without becoming instruments of oppression.
