Phototropism is a growth movement by plant part in the direction of the light. The stimulus for phototropism is a hormone that is present at the tip of the stem and is responsible for bending towards light. When the tip of stem is cut, the decapitated plant does not bend towards light because of lack of hormone at the tip.

Thus, the correct answer is option C.
