I think the Answer is D

A and B has an subject verb issue. makes v. make. The subject is plural therefore make is preferred. Eliminate A and B.

Both C and E have an ambiguous pronoun issue. Specifically who is "they" referring to? The people or the food? Therefore eliminate.

Pick D!

The answer is D.

The main statement has a S-V agreement problem. The plural subject, spicy foods needs a plural verb (make) - this eliminates A & B.
Choice C makes use of the pronoun 'they' for Habaero pepper. This is incorrect because 'they' can refer only to people and not objects. Choice E can also be eliminated for the same reason.
