The process in photosynthesis that uses energy from the Sun is **D combining carbon dioxide and hydrogen**. Specifically, this occurs during the Calvin cycle where the energy from sunlight, captured by chlorophyll, is used to convert carbon dioxide (from the atmosphere) and hydrogen (derived from splitting water) into glucose.
However, it can be noted that splitting water into hydrogen and oxygen (C) also relies on sunlight, specifically during the light-dependent reactions, but the option referring to the combination (D) is the primary example of utilizing solar energy for synthesizing organic molecules.
