(c) Both the size and shape of the shadow of the tree change.
(d) Neither the shape nor the size of the shadow changes.
Option (c) is the correct answer.
Since the position of the sun changes during the day, the size and shape of the shadow of the tree change. At 8:00 am and 3:00 pm, the lengths of the shadows of the tree will be longer than its actual length and is pointed towards West and the East directions, respectively. However, at 12:00 noon, the sun will be just above the tree, so the shadow of the tree will be short.
