Correct Answer: She asked me if I could look after her baby for a short while.

Solution : The fourth option is correct.

Indirect speech, also known as reported speech or indirect discourse, is a way of reporting what someone else has said without quoting their exact words.

Narration conversion:

• In yes-or-no questions, the connector if/whether is used to introduce the reported clause.
• "Said to" will get replaced with "asked".
• The second person "you" pronoun changes to the first person pronoun "I" in the indirect speech.
• "Can" changes to "could" .

Therefore, the indirect speech would be: S he asked me if I could look after her baby for a short while .
