Which of the following are products of photosynthesis?

Explanation:
Photosynthesis turns light energy into chemical energy stored in sugars, with oxygen released as a byproduct. In the chloroplasts, plants use light to drive reactions that combine carbon dioxide and water into glucose, a sugar, and release oxygen gas. That’s why the products are sugar (glucose) and oxygen. The other options describe inputs (water and carbon dioxide) or energy in a non-chemical form, or substances not produced by this process. Overall, the equation is: 6 CO2 + 6 H2O + light → C6H12O6 + 6 O2.
