Answer: Option B.
harvest photons and transfer light energy to the reaction-center chlorophyll
Explanation:
In the thylakoid membranes,the main role of the antenna pigment molecules is harvest photons and transfer light energy to the reaction-center chlorophyll because the photon of light move until it get to a molecule in the chlorophyll. When it reaches the molecule, it causes an excitation of electrons in the chlorophyll. The energy then present allow it to break free from the chlorophyll atom, which indicate chlorophyll donating an electron and the energy that is absorbed is then converted to heat.
