How Do Carotenoids and Phycobilins Assist in Photosynthesis

How do carotenoids and phycobilins assist in photosynthesis?

A) They bind to the chlorophyll and increase the surface area for photon absorption.
B) They absorb wavelengths of light not readily absorbed by chlorophyll.
C) They produce chemical energy and release solutes to rapidly open and close stomata.
D) They have a lower absorption efficiency but a higher tolerance to adverse environmental conditions, allowing the plant to continue some photosynthesis even under extremely harsh conditions.
E) Being structurally distinct from chlorophyll, carotenoids and phycobilins do not compete with chlorophyll for the same limited enzyme capacity.
