Femi, Tom is Aka's son … ?

Analyze the question

The sentence is "Femi, Tom is Aka's son, ........?" It needs a question tag. "Femi" is just the person being addressed (direct address), so it doesn't affect the tag.

Explain the concept

A question tag is a short question added to the end of a statement. The rules are:

1. Use the same auxiliary or verb as the main statement.
2. Use a pronoun that matches the subject.
3. If the statement is positive, the tag is negative. If the statement is negative, the tag is positive.

Step-by-step solution

• Statement: "Tom is Aka's son" is positive, so the tag must be negative.
• The verb is is, so the tag uses isn't.
• The subject is Tom (a male person), so the pronoun is he.
• Tag: isn't he?

Full sentence: Femi, Tom is Aka's son, isn't he?

Checking the options

• A. is he is a positive tag after a positive statement, so it is wrong.
• B. isn't it uses the wrong pronoun, because Tom is a person (he), not a thing.
• C. isn't he is a negative tag with the correct pronoun, so it is correct.
• D. he is is not a question-tag structure, so it is wrong.

Correct answer: C. isn't he

Exam tip: For tag questions, ask yourself three things: Is the statement positive or negative (so flip it)? What is the verb? What is the subject pronoun? Ignore any name used only to address someone, like "Femi" here.
