with the change in the time the direction of sun also changes hence the direction of source of light changes. Therefore the shape and size of the shadow changes.

● Option (a) : above option is not correct because it says that shape of the shadow will change but size will not change.

● Option (b) : above option is not correct because it says that size of the tree will change but shape of the shadow will not change.

● Option (c) : since both size and shape of the shadow changes. Therefore the option (c) is the correct answer.

● Option (d) : above option is not correct because it says that neither size nor shape of the shadow will change.
