The answer is a. True.
The photosynthesis occurs in leaves, which absorb sunlight. But the amount of absorbed sunlight by leaves depends on both the leaf surface area and intensity of life. So, the leaf surface area is just as important as the intensity of light in photosynthesis. But, if we take into consideration other leaves' functions, such as gas exchange, then the intensity of light has no effect on it. Thus, in that case, the leaf surface area is more important than the intensity of light.
