Correct option is D
The correct answer is (d) ) I, III, IV, II
Explanation (with years):
Dadra & Nagar Haveli became a Union Territory – 1961 Tenth Schedule added (Anti-defection) – 1985 (through 52nd Constitutional Amendment) Sindhi added to Eighth Schedule – 1967 (through 21st Constitutional Amendment) Sikkim became a full-fledged state – 1975 (36th Constitutional Amendment)
Arrange these chronologically (earliest → latest):
1. 1961 → I (Dadra & Nagar Haveli UT)
2. 1967 → III (Sindhi added to Eighth Schedule)
3. 1975 → IV (Sikkim became a state)
4. 1985 → II (Tenth Schedule added)
So the correct order is: I → III → IV → II
