It's C. The mass and speed of an object.

There are mainly two factors on which Kinetic Energy (denoted by KE) of an object depends - the mass (m) and speed (v) of the object. If the mass and speed of an object will increase, its KE will also increase.

The equation which is used to represent the relationship between mass, speed, and KE of an object is as follows:

KE = 0.5 • m • v2

where,

m = mass in Kilogram (kg) and v = velocity in m/s.

This equation also represents that KE is directly proportional to the square of its speed.

Answer: it it the mass and speed of an object
Why: beacause you need mass and speed to move an object or yourself
Example: you use your muscles to move a cabinet
