Technician A hydraulic fluid can transmit motion and force because a fluid cannot be compressed. Technician B says mechanical advantage in a hydraulic system is proportional to the size of the input piston versus the output piston. Who is correct?
A)A only
B)B only
C)Both A and B
D)Neither A nor B

Technician A is correct in stating that hydraulic fluid transmits motion and force because it cannot be compressed. This means that the force applied to the input piston is transferred to the output piston without any loss due to compression of the fluid. 
Technician B is also correct in stating that the mechanical advantage in a hydraulic system is proportional to the size difference between the input and output pistons. The larger the output piston, the greater the force that can be exerted, while the smaller input piston requires less force to be applied. Therefore, the ratio of the area of the output piston to the area of the input piston determines the mechanical advantage of the system.
