Choose the most suitable option to replace the highlighted part of the sentence: She has a car, isn’t it?
- (a)doesn't she?
- (b)hasn’t she?
- (c)isn't she?
- (d)has she not?
Answer
Why
Correct — A. A positive statement takes a negative tag: the statement's auxiliary plus a pronoun for its subject.
In 'She has a car', has is the main verb, meaning possess. The sentence is present simple with no auxiliary, so the tag borrows do: with she, that is doesn't.
The pronoun is she, the subject, not it.
Tag: doesn't she? → option (a).
Why the others are wrong
- (b)hasn’t she? — hasn’t she? treats has as an auxiliary, as in 'She has left, hasn't she?'. Here has is the main verb, and the standard tag for a main verb in the present simple takes do.
- (c)isn't she? — isn't she? builds the tag from be, but the statement has no be-form: its verb is has. It fixes the stem's it and keeps the stem's is.
- (d)has she not? — has she not? is the same have-tag as (b), uncontracted. It shares the same problem: has is the main verb here, so the standard tag is built with do.
Concept
A question tag is a short question added to a statement: an auxiliary plus a pronoun. A positive statement takes a negative tag, as in 'She can drive, can't she?'.
The tag copies the statement's auxiliary, and a main-verb be copies itself: 'It is late, isn't it?'. When the verb is present or past simple with no auxiliary, the tag uses do, does or did: 'He reads a lot of books, doesn't he?'.
So find the statement's verb before building the tag.
Wiktionary notes that lexical have, unlike other main verbs, can skip do in certain dialects, set expressions and literary use: 'Have you an idea?', 'I haven't the faintest idea'. A tag like hasn't she? rests on that usage.
The standard form, with do, is doesn't she?, and it is the one the key takes.
Key facts
- A positive statement takes a negative tag: She can drive, can't she?
- With no auxiliary in the statement, the tag uses do, does or did: He reads a lot of books, doesn't he?
- Has as a main verb means possess (She has a car). As an auxiliary it builds the perfect (She has left).
- The tag pronoun matches the subject: she, not it.

Common traps
- Copying has into the tag without checking whether it is the main verb or an auxiliary.
- Keeping it from the stem's tag when the subject is she.
Here the tag is the highlighted part of a sentence-improvement item, so the stem's own tag, isn’t it?, is the error to replace.
