If there is no tricks that after reading the question two times the answer is as follows

forget about the fixed portion of the salary and consider the variable part

1) if s = 5 therfore the variable part is 1
2) if s = 1 therfore the variable part is zero

thus the difference is 1 dollar.

I got B also.
I could find no way for the answer to be C other than if there is a mistake in the question.

(B) it is. It cannot possibly be C. This is another way of doing it:

Differentiating, we get: delta(p)= 0 + 0.25*delta(s)
Thus, d(p)=0.25(5-1)=1
The change in hourly rate is $ 1.00
