Solution

The correct option is A IAA
Phototropism is the ability of any organism to show movement in the direction of light. It is most often observed in plants but can also occur in other organisms such as fungi. Phototropism is promoted by a phytohormone, auxin. It is a natural hormone which is produced in the plants. The accumulation of the hormone in the opposite direction allows the bending of the shoot in the direction of the sunlight.
Thus, the correct answer is option A.
