the answer is B as all the other options contain quantities not related to describing motion

Quantities that can be used to describe motion are B: speed and acceleration.

What is defined as motion of an object/ body?

Motion is a change in position of an object over time. Motion is described in terms of displacement, distance, velocity, acceleration, time and speed.

Mass remain same , no matter where the object is taken . Whether the object is in motion or rest , its mass will remain constant , hence mass can never be used to describe the motion of an object and weight can not describe motion as weight is defined as the force of gravity with which a body is attracted to Earth , hence will not describe motion .

speed is the the rate at which someone or something moves or operates or is able to move or operate hence speed is used to describe the motion of an object

Acceleration is defined as the change in the velocity of an object with respect to time hence , it also have velocity in its formula which describes motion

hence correct option is B: speed and acceleration
