Select the correct indirect form of the given sentence.

He said to me, “Can you do these sums for me?”

He asked me if I could do those sums for him.

The correct indirect form of the given sentence is:

He asked me if I could do those sums for him.

The other options are incorrect for the following reasons:

• He asked me if I can do those sums for him. - The present tense modal verb "can" is not appropriate in indirect speech, as the speaker is reporting what was said in the past.
• He asked me if I can do these sums for him. - The word "these" is incorrect, as the speaker is asking the listener to do sums that are not directly present in the indirect speech sentence.
