The right option is; light and dark reactions
Photosynthesis is a chemical process by which plants and other photoautotrophs generate carbohydrates and oxygen from carbon dioxide, water, using light energy in chloroplasts. During the process of photosynthesis both light and dark reactions takes place in the chloroplast. The light reactions depends on light to produce organic energy molecules (ATP and NADPH) which are stimulated by chlorophyll (green colored pigment) while the dark reactions is light independent.
