The answer is letter D. Light intensity has an impact on the rate of photosynthesis. At low intensity of light, when the light intensity inscreases then the photsyntesis rate will also increase together with other factors. When there is more light that is being absorbed by the plant, the greater the rate of photosynthesis and the production of chlorophyll. But if the intensity will be increased, then there is a limiting factor in the rate of photosynthesis because hgih intensity can damage the chlorophyll.
