Answer

The process of photosynthesis is divided into two primary phases: light-dependent and light-independent phases. In the light-dependent phase, sunlight is utilized in the presence of chlorophyll to drive the reactions that produce chemical energy, specifically in the form of NADPH and ATP. These are essential molecules that act as energy carriers.

During the light-independent phase, also referred to as the Calvin cycle or dark phase, the energy stored in ATP and the reducing power of NADPH are used to convert carbon dioxide (CO2) into glucose. This phase doesn't require light and focuses more on using the chemical energy generated previously to synthesize food for the plant.

Given the options: A. RUBP and ATP
B. $\mathrm{H}_{2} \mathrm{O}$ and $\mathrm{O}_{2}$
C. NADPH and ATP
D. ATP and $O_{2}$

The correct answer is Option C (NADPH and ATP), as these are the products of the light-dependent reactions utilized in the light-independent phase for the synthesis of glucose.
