Answer:
B) harvest photons and transfer light energy to the reaction-center chlorophyll
Explanation:
The antenna pigment molecules form a complex which is known as the light-harvesting complex.
There are three antenna pigment molecules present in plants :
1. chlorophyll b
2. xanthophylls
3. carotenes
In one complex there can be 250 - 400 pigment molecules present which acts collectively to absorb energy and transfer it to the reaction center which consists of the chlorophyll.
This reaction center is responsible for capturing light energy in the form of chemical bonds.
