Which of the following is NOT correctly matched?

The correct answer is C. Allocation of seats in the Council of States (Rajya Sabha) is in the Fourth Schedule, not the Second. The Second Schedule deals with salaries and allowances of constitutional functionaries such as the President, Governors, Speakers, judges of the Supreme Court and High Courts, and the CAG.

The other three pairs are correct. Public health and sanitation is entry 6 of the State List, which is why states run hospitals and sanitation programmes. Census is entry 69 of the Union List, so only Parliament can legislate on it. Anti-defection is in the Tenth Schedule, inserted by the 52nd Amendment in 1985.

The core concept is the Seventh Schedule's three lists and how they divide powers between Centre and states. This links directly to the Mains theme of federalism and the debate on centralisation through Union List entries and Article 249.

Trap: Candidates memorise schedules in sequence and confuse the Second and Fourth. Remember that the Fourth Schedule is tied to Rajya Sabha seat allocation.
