Which one of the following statements about the process of photosynthesis is correct?

Options

  1. AChemical energy is converted into light energy.
  2. BCarbon dioxide is oxidised to form carbohydrate.
  3. CWater molecule splits into hydrogen and oxygen.
  4. DLight energy is directly used to split water.

Correct answer

C. Water molecule splits into hydrogen and oxygen.

Step-by-step solution

In the process of photolysis ('light' and 'split'), light energy and catalysts interact to drive the splitting of water molecules into protons ( H ⁺ ) , electrons, and oxygen gas. Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
