Answer:
can I?
Explanation:
A question can be defined as a statement that begs or requires an answer, response or reply.
Generally, there are four (4) main types of question and these includes;
I. Rhetorical question.
II. Close-ended question.
III. Open-ended question.
IV. Between the lines question.
A question tag can be defined as a very short clause placed at the end of a sentence (statement) which changes it to a question. Some examples of tags used in English language are: can we, can't we, should I, aren't they, shouldn't they, wouldn't it, weren't they, do I, shall we, etc.
In the scenario, the most appropriate or suitable tag to complete the question is "can I?"
Therefore, the complete question is written as;
"I want to return the sweater, can I?"
