If we suspend a weight using a spring, as shown in the given figure -
What kind of changes are involved in this?
Both (A) and (C)
From the figure, it is evident that as soon as the weight is applied to the spring balance by human effort, the spring stretches and moves in the downward direction. Hence, a man-made change. Also, if the weight is removed, the spring will revert to its original shape, hence also a temporary change.
