Correct Answer: He enquired whether his name was not Ahmed.

Solution : The correct choice is the second option .

In reported speech, the tense of the reporting verb often changes according to the sequence of tenses. When the reporting verb is in the past tense, the verb tenses in the reported speech also shift to the past.

When transforming this sentence into indirect speech -

• The reporting verb "said" changes to "inquired" as it is an inquiry.
• The pronoun "him" (the person being spoken to) remains unchanged.
• The question mark and quotation marks are removed in indirect speech.
• The question "Is your name not Ahmed?" becomes a subordinate interrogative clause: "whether his name was not Ahmed".

So, the indirect speech version becomes: "He inquired whether his name was not Ahmed."
