There are hundred of superstitions that survive in various parts of the country, and the study of them is rather amusing.

Correct option is D

The correct substitution of the highlighted words is (d) There are hundreds of superstitions that survive in various parts of the country, and the study of them is rather amusing.
Explanation: When referring to an indefinite large number, we use the plural form with -s plus of: hundreds of, thousands of, dozens of.
Here, the intended meaning is “a large number of superstitions,” so hundreds of superstitions is correct. The verb survive correctly agrees with the plural noun superstitions, and present simple is apt for a general fact. The phrase the study of them is fine, with them referring back to superstitions.
Grammatical rule used:
· Exact number: one/two/three hundred (no s) — e.g., two hundred rupees.
· Indefinite large number: hundreds/thousands of + plural noun — e.g., hundreds of books.
· Subject–verb agreement: plural subject → plural verb (superstitions survive).
Example: Thousands of tourists visit the fort every year.
Information booster: Similar quantifiers: dozens of, scores of, heaps of, loads of. Avoid hundred of (incorrect) and hundreds of superstition (noun must be plural: superstitions).
