C Correct answer
Explanation

Cholodny-Went Theory explains phototropism (bending toward light) through unequal auxin distribution - more auxin accumulates on the shaded side causing cells to elongate more. Photomorphogenesis is light-mediated development, photoperiodism is response to day length, and photorespiration is a wasteful process in C3 plants.
