How many schedules does The Constitution of India contain?

The correct answer is Option (4) → 12

The Constitution of India originally had eight schedules; four more were added by amendment, so it now contains twelve. The Ninth came with the First Amendment of 1951, the Tenth with the anti-defection provisions of 1985, and the Eleventh and Twelfth with the Panchayat and Municipality amendments of 1992.

The schedules are the lists and tables attached to the Constitution — the states and union territories, the salaries of officials, the oaths, the union and state lists, the languages, and the powers of local bodies.
