Quizplus · Accepted Answer

Chlorophyll a and b are the primary pigments responsible for absorbing light in the process of photosynthesis. This light energy is then used to drive the conversion of carbon dioxide and water into glucose and oxygen. Without absorption of light by chlorophyll a and b, photosynthesis cannot occur. Reflection and transmission of light are also important processes, but they are not as essential to photosynthesis as absorption. Therefore, choice B is the best answer.
