Solution

The correct option is A It decreases in size.
Shadows usually get larger when the source of light gets closer to the object, and they get smaller when the source moves far away. Hence, when the torch is moved away from the object, the size of shadow would decrease. The shape of the shadow might change into an ellipse, but never it becomes a rectangle.
