Results of the recent study make it mandatory that the Surgeon General

The subjunctive is not relevant to the plurality of the verb.

The Surgeon General is the subject you need agreement with.

Dear Friends,

Here is a detailed explanation to this question-


Choice A: This answer choice features a subject-verb disagreement between "the Surgeon General" and "rejects"; the use of the phrase "make it mandatory" means that the subjunctive mood applies to the verb "rejects", as this phrase conveys a sense of authoritative command, meaning that this verb must be in the plural form. Thus, this answer choice is incorrect.

Choice B: This answer choice features a redundancy in its use of the word "should"; this word conveys a sense of obligation, as does the word "mandatory" found in the non-underlined portion of the sentence. Thus, this answer choice is not a very good one.

Choice C: This answer choice maintains subject-verb agreement, preserves the intended meaning of the sentence, and is quite concise. Thus, this answer choice is correct.

Choice D: This answer choice showcases a similar redundancy error to the one found in Option B, due to the use of the word "must". Thus, this answer choice is not a very good one.

Choice E: This answer choice changes the meaning of the sentence by shifting it into the future tense through the use of the verb "will reject". Thus, this answer choice is incorrect.

Hence, C is the best answer choice.
