The correct answer is A. Rohit asked me if I had read that novel.
The sentence “Have you read this novel?” is in the present perfect tense. The present perfect tense is used to talk about things that have happened or been true up to the present moment. In this case, Rohit is asking me if I have read the novel at any point in the past.
Option B is incorrect because the present perfect tense is not used to talk about things that are possible or probable.
Option C is incorrect because the present perfect tense is not used to talk about things that are hypothetical or uncertain.
Option D is incorrect because the present perfect tense is not used to talk about things that are happening right now.
