Correct Answer: The boy said, "Why didn't you wake me up, mother?"

Solution : The correct choice is the third option.

Explanation:
Direct form refers to the representation of spoken or written words exactly as they were originally expressed by the speaker or writer. In grammar and linguistics, direct form is often associated with direct speech or direct quotations.
Narration Conversion:

• Change the reporting verb, asked to said.
• Introduce the reported speech using quotation marks.
• Adjust the pronouns accordingly: "Third person pronoun (his)" becomes second person pronoun (you)".
• Transform the sentence from indirect to direct speech by rephrasing the question.
• The original words of the speaker are enclosed in inverted commas.

Therefore, the correct direct form would be: The boy said, "Why didn't you wake me up, mother?"
