Subject-verb agreement is tested in this question. The sentence is in the present tense, so the verb tense used should also be in the present tense.
Explanation of options:
a)are said / could be published - Incorrect. The use of "could" is incorrect here as it indicates a possibility, and the sentence needs to reflect a fact. Also, "are said" is in the present tense, but "could be published" is in the conditional tense, making the sentence grammatically incorrect.
b)say / can be published - Correct. "Say" is in the present tense, and "can be published" is in the present tense, making the sentence grammatically correct.
c)will say / had been published - Incorrect. "Will say" is in the future tense, but the sentence is in the present tense. "Had been published" is in the past perfect tense, which is incorrect in this sentence.
d)said / may be published - Incorrect. "Said" is in the past tense, which is incorrect as the sentence is in the present tense. "May be published" is in the conditional tense, which is not suitable for this sentence.
e)have said / should publish - Incorrect. "Have said" is in the present perfect tense, which is incorrect in this sentence. "Should publish" is in the conditional tense, which is not suitable for this sentence.
Therefore, option (b) is the correct answer.
