the table below shows the role of different substances during photosynthesis.

substance	role during photosynthesis
water	combines with carbon dioxide to form glucose
chlorophyll	combines with water to form oxygen

Explanation:

The reactants of photosynthesis are carbon - dioxide ($CO_2$), water ($H_2O$), and energy (from sunlight). The overall chemical equation for photosynthesis is $6CO_2 + 6H_2O+\text{Energy}
ightarrow C_6H_{12}O_6 + 6O_2$. Option a has the correct amounts of reactants and energy. Option b lists products of photosynthesis. Option c has the correct substances but not the correct stoichiometry as in the full - balanced equation. Option d lists products.

Answer:

A. $6CO_2 + 6H_2O + \text{Energy}$
