a / the

If you let me make a choice between Jane and Anne, I would say Jane is ______ one to be my assistant.
A.a good
B.a better
C. the better
D.the best
The answer is C.

I totally agree that the answer is C.
My question is, Is choice B used when there are two or more better ones? If there are Jane, Anne, Mary, and somebody else, then can I choose B ? (and D,for sure)

Many thanks in advance.
