The sentence is talking about the critics and their opinion on a review. Let's break down the options and analyze them one by one:
A.
are said / could be published
- "are said" is incorrect because it is in the present tense, but we need a past tense verb to match with "that" in the sentence.
- "could be published" is grammatically correct, indicating a possibility, but it does not match the verb tense needed in the sentence.
B.
say / can be published
- "say" is the correct verb form in the present tense to match with "that" in the sentence.
- "can be published" is grammatically correct, indicating a possibility, and it matches the verb tense needed in the sentence.
C.
will say / had been published
- "will say" is incorrect because it is in the future tense, but we need a present tense verb to match with "that" in the sentence.
- "had been published" is incorrect because it is in the past perfect tense, but we need a simple past tense verb to match with "that" in the sentence.
D.
said / may be published
- "said" is the correct verb form in the past tense to match with "that" in the sentence.
- "may be published" is grammatically correct, indicating a possibility, and it matches the verb tense needed in the sentence.
E.
have said / should publish
- "have said" is incorrect because it is in the present perfect tense, but we need a simple past tense verb to match with "that" in the sentence.
- "should publish" is incorrect because it is in the present tense, but we need a past tense verb to match with "that" in the sentence.
Therefore, the correct answer is B.
say / can be published
