D Correct answer
Explanation

Photosynthesis is reductive because it reduces CO2 to carbohydrate (adding electrons/hydrogen). It is endergonic because it requires energy input (light energy to drive the process). It is anabolic because it builds complex glucose molecules from simple CO2, breaking down water in the process. Endergonic reactions always require energy input, unlike exergonic reactions that release energy.
