and I don't want
one as well
No error

The correct answer is D. No error.

The sentence “I don’t have a car and I don’t want one as well” is grammatically correct. The conjunction “and” is used to join two independent clauses, and the adverb “as well” is used to add emphasis to the second clause.

Option A is incorrect because it does not include the conjunction “and.” Option B is incorrect because it does not include the adverb “as well.” Option C is incorrect because it does not include the verb “want.”
