Why Are the Reaction Centres of Photosystems Composed of Several

Why are the reaction centres of photosystems composed of several structurally different pigments?

A) Excited electrons must pass through several pigments before they can be transferred to electron acceptors of the electron transport chain.
B) This arrangement enables the plant to absorb light energy of a variety of wavelengths.
C) This arrangement enables the plant to absorb more photons from light energy, all of which are at the same wavelength.
D) This arrangement enables the reaction centre to excite electrons to a higher energy level.
