Step 1: Change the reporting verb. 'said to' changes to 'asked' because it's a question.
Step 2: Introduce a conjunction. For yes/no questions, we use 'if' or 'whether'.
Step 3: Change tense and pronouns. The verb 'has come' (Present Perfect) should ideally change to 'had come' (Past Perfect). The pronoun 'your' changes to 'his'. The sentence becomes: "Rima asked Mohan if his result had come out."
Step 4: Evaluate the options. None of the options correctly use the Past Perfect tense. Option (B) is the closest, as it correctly changes the reporting verb and pronoun, but it fails to backshift the tense of 'has come'. Among the given choices, it remains the best fit despite this grammatical imperfection. The marked answer (A) is incorrect because it changes 'said' to 'says' and uses the wrong verb 'are'.
