Answer:

A) red light

Explanation:

Blue light is absorbed not only by chlorophyll, but also by carotenoids, and some carotenoids are not in the chloroplasts; further, carotenes and xanthophylls make up the carotenoids. Carotenes do not transfer absorbed energy efficiently to chlorophyll, and thus some part of absorbed blue light is not going to photosynthesis. On the other hand, all of red light is absorbed by chlorophylls and used effectively.

The rate of photosynthesis is greatest under red light.

Red and blue light are both absorbed by the xanthophylls and carotenes. The absorption of blue light is higher than that of red light in the xanthophylls and carotenes.

However, red light is solely absorbed in the chlorophyll and not blue light. As such, the absorbed red light is utilized for photosynthesis directly.
