During Photosynthesis,plants Use Light Energy to Synthesize Glucose from Carbon

During photosynthesis,plants use light energy to synthesize glucose from carbon dioxide.However,plants do not use up energy during photosynthesis; they merely convert it from light energy to chemical energy.This is an illustration of:

A) spontaneous reaction.
B) chemical equilibrium.
C) the second law of thermodynamics.
D) the first law of thermodynamics.
E) increasing entropy.
