Correct Answer: The doctor asked Rahul how he was feeling that day.

Solution : The correct choice is the second option.

Reported speech is the form of speech used to convey what was said by someone at some point in time.

The steps of conversion are as follows:

• The reporting verb "asked" remains the same in the indirect speech in the case of the interrogative sentence.
• The pronoun "you" (second-person pronoun) is changed to "he" (third-person pronoun) in the indirect speech.
• Since the direct speech is in the present tense, it is changed to the past tense in the indirect speech. So, the verb "is" is changed to "was".
• "Today" in the direct speech is changed to "that day".

So, the correct sentence would be: "The doctor asked Rahul how he was feeling that day."
