Correct Answer: The boss said to Anita that he wanted to speak to her.

Solution : The fourth option is the correct answer.

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 the indirect form, we use "said to Anita" to indicate that the boss spoke to Anita.
• The first person pronoun " I" changes to the third person pronoun "he".
• The simple present tense " want " changes to the simple past tense "wanted " in the indirect speech.
• The second person pronoun "you" changes to the third person pronoun "her".

Therefore, the indirect form would be: The boss said to Anita that he wanted to speak to her.
