Detailed Explanation:

Answer: Option 4 — 1, 2 and 3

Article 368 of the Indian Constitution provides Parliament with comprehensive powers to amend the Constitution through three distinct methods: addition (inserting new provisions), variation (modifying existing provisions), and repeal (removing provisions). This flexibility ensures the Constitution remains a living document capable of adapting to changing social, political, and economic needs while maintaining constitutional continuity.

✅ Statement 1 (Addition) – Correct: Parliament can add new provisions to the Constitution, such as the insertion of Article 15(5) through the 93rd Amendment Act, 2005, allowing reservations in educational institutions.

✅ Statement 2 (Variation) – Correct: Parliament can modify existing constitutional provisions, as demonstrated by the 42nd Amendment Act, 1976, which altered the Preamble and various other articles.

✅ Statement 3 (Repeal) – Correct: Parliament can remove constitutional provisions entirely, exemplified by the 26th Amendment Act, 1971, which abolished privy purses for former rulers of princely states.
