Select the opinion that will improve the underline part of the sentence. In case no improvement is needed, select ‘No improvement’. His tone was neither of anger nor sorrow.

Correct answer: nor of sorrow

Explanation: The correct answer is D.✅ The correct correlative conjunction pair is "neither...nor", and parallel structure must be maintained. Since "of anger" is used, the second part should also use the same preposition "of" for balance. Correct sentence: His tone was neither of anger nor of sorrow. ❌"Or sorrow" and "or of sorrow" are incorrect due to the wrong pairing with "neither". ❌"No improvement" is incorrect because the sentence lacks parallel structure. ❌"Nor of sorrow" maintains proper grammatical and stylistic balance.
