The correct answer is A. one half step up from the last sharp.

To determine the key in key signatures with sharps, you can follow these steps:

1. Identify the last sharp in the key signature.
2. Move one half step up from the last sharp to determine the key.

For example, if the last sharp is F♯, then moving one half step up from F♯ will give you the key of G major.

So, in this case, the correct answer is A. one half step up from the last sharp.
