in the first place A. first B. later C. same D. final

The correct answer is A. first.

Explanation:
The phrase "in the first place" means at the beginning or to start with.
It is used to refer to the initial stage of something or to emphasize the first of several reasons or points.

Example:

"Why didn’t you tell me you were leaving in the first place?"
That means: why didn’t you tell me at the very beginning?

Thus, "first" is the word that matches the meaning.
