Detailed Explanation:

Adjournment Motion is an extraordinary parliamentary device used in the Lok Sabha only (not in Rajya Sabha) to discuss a definite matter of urgent public importance. It interrupts the normal business of the House and is considered a tool of censure against the government, requiring support of at least 50 members for admission.

❌ Option 2 – Incorrect: Question Hour and other devices are used for collecting information from ministers, not adjournment motion.

❌ Option 3 – Incorrect: This describes Cut Motion, which is used to reduce specific amounts in demand for grants during Budget discussion.

❌ Option 4 – Incorrect: This describes Adjournment of the House, a power exercised by the Presiding Officer to suspend sitting due to disorder or lack of quorum, not a motion moved by members.
