Solution

The correct option is D
Auxin

The phototropic curvature is the result of uneven distribution of auxins. Phototropism is the growth of an organism in response to light stimulus. During phototropism, the auxin concentration in stem cells is usually higher on the side of the stem away from light. These cells will stretch more during active growth, causing the plant to move towards the light source.
