Correct Answer: Mary says that her younger brother wants to be a radio jockey.

Solution : The correct choice is the first option.

The indirect form of a sentence involves reporting or paraphrasing what someone else said without using their exact words. It often involves a shift in tense, pronouns, and sometimes the structure of the reported sentence. The steps are as follows:

• "Says" and "wants" don't change here because when the reporting verb is in the present tense, the tense doesn't change.
• "My" is changed to "her" because the first-person pronoun is changed to the third-person pronoun.
• The quotation marks are removed, and the statement is no longer presented as a direct quote but as a reported speech.

Therefore, the indirect form would be: "Mary says that her younger brother wants to be a radio jockey."
