Answer:
The correct answer will be option C (Chloroplasts).
Step-by-step explanation:
Chloroplasts are the cell organelles which contains pigment which can absorb light from the sun and use it to make food.
Though light acts as a substrate for photosynthetic energy conversion, too much of light can harm plants as too much light damage and degrade the reaction center of PS II (water-splitting photosystem) in the chlorophyll.
It produces highly oxidizing radicals and toxic reactive oxygen species (ROS) which can damage the cell.
So, plant shows movement of chloroplast in response to high light as an adaptive mechanism by accumulating along the walls in parallel orientation to the incident light.
Thus, option C (Chloroplasts) is the correct answer.
