Answer:
It should be d -- photosynthesis.
Step-by-step explanation:
Fermentation is changing something from one organic to another using enzymes. There is chemical energy involved, but light is not.
Cellular respiration does involve chemical change but the products are CO2 and water. The change creates energy, but light is not involved.
There is a chemical change in Glycolysis. This process breaks down the simple sugars to produce 2 molecules each with 3 Carbons and again light is not involved.
The answer is photosynthesis. This involves light and chemical change.
