Answer 2

Answer:

Tree forms the darkest shadow when a light source is obstructed.

Explanation:

A dark shadow is formed when an object blocks the light source. To form a dark shadow object should be opaque or translucent. Tree is opaque object and it can block the light from passing through it. Therefore when light falls on the tree it will produce a dark shadow. Other options which are given cannot make dark shadow as they are transparent object and when light falls on such objects it will pass through it.
