The correct answer is B) has decided whether to attend the graduation ceremony.
Explanation:
The subject of the sentence is the compound subject "Neither Sarah nor her parents." In English grammar, when we use "neither...nor" to connect two subjects, the verb should agree in number with the closest subject. In this sentence, "parents" is plural, but "Sarah" is singular, and "Sarah" is closer to the verb "has" than "parents." Therefore, we need a singular verb "has" to match the singular subject "Sarah."
Answer A) "have decided whether to attend the graduation ceremony" uses a plural verb form "have," which does not agree with the singular subject "Sarah."
Answer C) "have decided if they will attend the graduation ceremony" is incorrect because it uses "if" instead of "whether." In English grammar, "if" is used in conditional sentences, while "whether" is used to introduce a direct question or indicate that two alternatives are being considered.
Answer D) "has decided if they will attend the graduation ceremony" is incorrect because it uses "if" instead of "whether."
Answer E) "have made a decision whether to attend the graduation ceremony" is incorrect because it changes the meaning of the original sentence. The original sentence indicates that no decision has been made yet, while this sentence implies that a decision has been made.
Therefore, the correct answer is B) "has decided whether to attend the graduation ceremony," which uses the correct singular verb form and the correct conjunction "whether."
