Option 1: Light energy is directly converted to kinetic energy which oxidizes carbon dioxide.

This statement is incorrect. During the process of photosynthesis, light energy is not directly converted to kinetic energy that oxidizes carbon dioxide. Kinetic energy refers to the energy of motion, and photosynthesis involves the conversion of light energy into chemical energy, not kinetic energy.

Option 2: Light energy is directly converted to chemical energy which causes reduction of water.

This statement is incorrect. Light energy is indeed converted to chemical energy during photosynthesis, but it does not directly cause the reduction of water. In photosynthesis, water molecules are split into hydrogen and oxygen through a process called photolysis, and the reduction of water occurs as a result of this process.

Option 3: Chlorophyll absorbs the chemical energy of light which causes oxidation of carbon dioxide.

This statement is incorrect. Chlorophyll absorbs light energy, not chemical energy. Additionally, during photosynthesis, carbon dioxide is reduced, not oxidized. The process of photosynthesis involves the reduction of carbon dioxide to form glucose, a type of chemical energy.

Option 4: Chlorophyll absorbs light energy which causes splitting of water molecules and reduction of carbon dioxide.

This statement is correct. Chlorophyll, the pigment
