Answer 1

A. a reference point is required to determine whether or not an object moves

Answer 2

The correct answer is option A. a reference point.

In order to determine, whether an object has moved or not, a point of reference is required. The reference point is required to the measure the movement of the object, without a reference point the distance or displacement cannot be obtained. Hence, a reference point is very required to determine, whether the object has moved or not.
