Correct Answer: I requested Sharma to give me his book.

Solution : The correct choice is the second option .

In the original sentence, the speaker directly quotes their words to Sharma using double quotation marks.

When transforming this into indirect speech:

• The reporting verb changes from " said " to " requested, " as the speaker is asking for the book using "please."
• The imperative "give me your book" is rephrased, and the pronouns are adjusted.

This maintains the meaning of the original sentence while conforming to the conventions of indirect speech, where the exact words are paraphrased within a reporting structure.

Therefore, the indirect sentence would be: "I requested Sharma to give me his book."
