A thesaurus can be a useful tool for writers, providing he knows how

Dear Friends,

Here is a detailed explanation to this question-



Choice A: This answer choice refers to the plural noun "writers" with the singular pronoun "he". Thus, this answer choice is incorrect.

Choice B: This answer choice repeats the error found in Option A. Furthermore, this answer choice needlessly utilizes the phrase "such a book" rather than the pronoun "it". Thus, this answer choice is incorrect.

Choice C: This answer choice uses the plural pronoun "them" to refer to the singular noun "thesaurus". Thus, this answer choice is incorrect.

Choice D: This answer choice repeats the error found in Option A by using the singular pronoun "she" to refer to the plural noun "writers". Thus, this answer choice is incorrect.

Choice E: This answer choice maintains agreement between all pronouns and the nouns that they refer to, throughout the sentence. Thus, this answer choice is correct.

Hence, E is the best answer choice.

All the best!
