What would happen if a hydraulic system had a leak and lost some of its fluid

a. The pressure would remain the same, but less force would be transferred.
b. The pressure would be reduced, and less force would be transferred.
c. The pressure would increase, and more force would be transferred.
d. There would be little or no effort.

b. The pressure would be reduced, and less force would be transferred.

Hydraulic systems rely on high working fluid pressures, so even a slight leak could cause a lot of fluid to leak out and reduce the available pressure and force.
