Concept:Question tags are short questions added to the end of a statement, usually to seek agreement or confirmation.
When the main statement is positive, the question tag is normally negative.
Explanation:The given sentence is: "You will help me lift this box, ___?"
The main statement, "You will help me lift this box," is positive because it uses "will help."
Therefore, the question tag should be negative.
The negative tag for "will" is "won't."
So the sentence becomes: "You will help me lift this box, won't you?"
The other options, "would you," "can you," and "could you," do not match the auxiliary "will" used in the statement.
Thus, the most appropriate option is "won't you."
Answer:A. won't you
