Which statement best describes the relationship of photosynthesis and energy?

the process of photosynthesis is energy-storing because the process converts light energy into chemical energy, which stored in the bonds of glucose.
the process of photosynthesis is energy-releasing because the process converts light energy into free energy that can be used for cell functions.
the process of photosynthesis is energy-conserving because no energy is used throughout the process of forming glucose and oxygen molecules.
the process of photosynthesis is energy-wasting because photosynthesis is ineff
