Explanation
This question is asking what pigment aids in capturing light to catalyze the process of photosynthesis. Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of pigments. These pigments absorb certain wavelengths of light to initiate the process. Hemoglobin (option A) is a protein in red blood cells that carries oxygen, glucose (option B) is a sugar used as an energy source by the cells, and melanin (option D) is the pigment responsible for hair and skin color in humans. Chlorophyll (option C) is the pigment essential for photosynthesis in plants and algae. It captures light most efficiently in the wavelengths best absorbed, thus facilitating the photosynthesis process.
