Refer to the drawing of a bellows-type differential pressure (D/P) detector (see figure below).
The spring in this detector (shown in a compressed state) has weakened from long-term use.
If the actual D/P is constant, how will indicated D/P respond as the spring weakens?
A. Increase, because the spring will expand more
B. Decrease, because the spring will expand more
C. Increase, because the spring will compress more
D. Decrease, because the spring will compress more
