The following sentence has been split into four segments. Identify the segment that contains a grammatical error.
They all, except Shirin, were very sad / during the farewell party given / to the teacher retiring, and her / indifference were well noticed.

Correct option is B

Option (b) contains an error.
Explanation:
· The subject of the clause is “indifference,” which is a singular noun.
· Therefore, it should be followed by the singular verb “was” instead of “were.”
· Correct sentence: “Her indifference was well noticed.”
Grammatical rule used:
✅ A singular noun must take a singular verb (Subject-Verb Agreement).
�� Information booster: Even when the subject is a non-living thing or an abstract noun like honesty, beauty, indifference, it still takes a singular verb.
