You . . . . . . . . not stay here. A. need B. can C. will D. would

The correct answer is: will not.

The sentence “You will not stay here” is a negative statement about the future. It means that you are not going to stay in the place where you are now.

The other options are:

• Need. This means that you are required to do something. In this case, it would mean that you are required to stay in the place where you are now. However, the sentence does not say that you are required to stay, so this is not the correct answer.
• Can. This means that you are able to do something. In this case, it would mean that you are able to stay in the place where you are now. However, the sentence does not say that you are able to stay, so this is not the correct answer.
• Would. This means that you are willing to do something. In this case, it would mean that you are willing to stay in the place where you are now. However, the sentence does not say that you are willing to stay, so this is not the correct answer.

Therefore, the correct answer is will not.
