Hydraulic jacks works on the Pascal's law that the pressure in closed container is the same at all points.

Power required to drive a centrifugal pump is directly proportional to the fourth power of the diameter of its propeller.

$\implies$   Greater the difference in the areas of the cylinder , greater is the force potential output of the big cylinder for hydraulic jacks.

The center of pressure of surface subjected to fluid pressure is the point on the surface at which gravitational force acts

The axial pump is a pump in which fluid flows axially to the rotation of the propeller. In Axial flow, the fluid flows parallel to the axis of rotation, as in a turbine. Axial flow pump contains a propeller or centrifugal impeller in the casing. Axial Flow pump is preferred for flood control and irrigation applications.

Slip of a reciprocating pump is defined as  Difference of theoretical discharge and actual discharge.

Jacks can be categorized based on mechanical and hydraulic forces.

The shaft in the floor jack is horizontal. Hence option B is correct.

Hydraulic jacks use pump plungers to move oil through two cylinders.

Two types of hydraulic jacks are commonly used- bottle jacks and floor jacks.
