Correct option is D

The correct substitution is (d) No improvement required.
Explanation: The subject “side effects” is plural, and the verb “include” correctly agrees with it. The sentence already uses the correct structure:
· “Side effects (plural subject) + include (plural verb) + object.”
· The verb “include” is correctly followed by a list of symptoms (burning and itching), making the original sentence grammatically accurate.
Grammatical rule used:
Subject-verb agreement: plural subjects take plural verbs.
· Correct: The side effects include fever and fatigue.
· Incorrect: The side effects includes fever and fatigue.
Example:
· The possible dangers include nausea and dizziness.
