Correct Answer

Explanation

Etiolation is caused by the influence of insufficient light. Etiolation is a phenomenon in plants characterized by pale coloration, elongated stems, and small leaves due to the plant's attempt to reach for more light. When plants don't receive adequate light, they elongate their stems in an effort to reach light sources, resulting in weak, spindly growth.
