Fill in the blanks with the most appropriate option:-

You need to go there, ………….. you?

don’t

The correct option to fill in the blanks is don't.

The sentence is a question that is asking the listener if they need to go somewhere. The verb "need" is in the present tense, singular form. The contraction "don't" is used to negate the verb "need" in the second person singular form. It is the most appropriate contraction to use in this context, as it describes the speaker's uncertainty about whether or not the listener needs to go somewhere.

The other options are not as appropriate:

• Do is the present tense, singular form of the verb "to do". It is not as appropriate as "don't", as it does not convey the same sense of negation.
• Does is the present tense, singular form of the verb "to do". It is not as appropriate as "don't", as it does not convey the same sense of uncertainty or politeness.
• Doesn't is the present tense, singular form of the verb "to do" with the negative prefix "not". It is not as appropriate as "don't", as it is more formal and less polite.
