In the following sentence, a part of the sentence may contain a grammatical error. Identify the segment that contains the error.

Neither the manager nor the team members (A)/ has submitted (B)/ their project reports (C)/ to the director on time. (D)/ No error

The correct option is B.

Explanation:
In the given sentence, part (B) contains a grammatical error.

Grammatical Rule (Subject-Verb Agreement):
When two subjects are joined by "Neither... nor...", the verb must agree in number with the subject that is closest to it (Rule of Proximity).

In the given sentence:
• First subject: "the manager" (Singular)
• Second subject: "the team members" (Plural, closest to the verb)

Since the closer subject "the team members" is plural, the auxiliary verb must also be plural ("have" instead of "has").

Correct Sentence:
"Neither the manager nor the team members have submitted their project reports to the director on time."

Hence, the error lies in segment (B).
