Correct Answer: Ravi asked me if I knew the house of my family doctor.

Solution : The correct choice is the first option.

In transforming direct speech to indirect speech, it is crucial to select the right reporting verb and make necessary adjustments in tense and pronoun references.

Narration Conversion:

• Asked is used as a reporting verb in the case of questions.
• If is used as a conjunction to connect the main clause to the relative clause, as it is a question.
• Know is changed to knew, which is the past tense as it is a case of indirect speech.
• Your is changed to my (second person changed to first person pronoun), as it is the correct possessive determiner in the case of indirect speech.
• The conjunction "if" is used in the case of yes or no questions.

Therefore, the sentence in indirect form is: Ravi asked me if I knew the house of my family doctor.
