Answer:
Option A , Light energy is converted to chemical energy during photosynthesis.
Step-by-step explanation:
In the process of photosynthesis, a plant containing chlorophyll converts solar light energy into chemical energy.
The common reaction of photosynthesis is
Carbon dioxide + Water + energy from sun ------> Glucose + carbon dioxide
Thus, energy from sun is used to excite photon with in the thalokoid of plant cell to initiate photosynthesis and then as a result of this process food (glucose containing chemical energy ) and carbon dioxide is formed.
Hence, option A is correct
