The substance that is one of the final products of photosynthesis is:
D. Sugar
During photosynthesis, plants use carbon dioxide, water, and sunlight to produce glucose (sugar) and oxygen. Glucose is a type of sugar that serves as the main source of energy for the plant and is used in various cellular processes. Oxygen is released into the atmosphere as a byproduct of this process. Therefore, sugar (glucose) is one of the key final products of photosynthesis.
