an object that is moving must have a change in
a) its speed.
b) its position.
c) its acceleration.
d) its applied force.

B ) position

Explanation:

moving object can have a constant speed ,constant acceleration and no change in the applied force

(when there is no applied force on the object  ,it keep its motion uninterruptedly - Newton's first law of motion )

But if an object is moving , it must change its position as if it is still remain in the same position , there can never be a motion at all
