Answer 1

The correct option is C

Shadows are formed when an opaque object comes in the path of light

A shadow is formed when the light is blocked by an opaque or translucent object. Opaque objects, such as a tree, completely block light and form a dark shadow. Translucent materials, such as tissue paper, allow partial light through, which scatters and creates a faint shadow. Transparent objects, such as glass, do not create a shadow because the light passes through in a straight line.
