We have to face frequently flood and droughts.

The correct answer is (d) frequent floods.
Explanation: The word "frequently" is an adverb, and it is modifying a noun, which is incorrect in this context. The adjective "frequent" should be used to describe the occurrence of "floods." Additionally, "floods" should be in its plural form to match "droughts."
· Frequenter flood: Incorrect, "frequenter" refers to a person who frequently visits a place.
· Frequently floods: Incorrect, as "frequently" is an adverb, not an adjective.
· Frequent floods: Correct, as "frequent" is the appropriate adjective to describe "floods."
Corrected sentence: "We have to face frequent floods and droughts."
