There are two sentences (S1) and (S2) based on commonly used word(s), which are highlighted. Read the two sentences carefully and mark the response that denotes the correct use of these words in each of the two sentences.
(S1): The teacher enquired whether there is any problem with the question paper.
(S2): He asked her whether she had some pets at home.

Correct option is B

(S1) is incorrect because it mixes tenses inappropriately. The teacher's inquiry is reported in the past tense ("enquired"), so the verb that follows should also be in a past tense form for consistency in reported speech. The correct sentence would be "The teacher enquired whether there was any problem with the question paper."
· (S2) is correctly phrased in the past tense, appropriate for reported speech. It accurately conveys a past inquiry about the possession of pets, using the correct tense "had" to match the reporting verb "asked."
· Thus, the correct response is that (S1) is wrong due to a tense consistency error, while (S2) is correctly structured.
