Answer:
D. Antenna pigments allow more wavelengths of light and more photons to be captured, increasing the efficiency of light capture.
Explanation:
The photosynthetic pigments can be part of the antenna pigments or part of the reaction center. The role of the antenna pigments (large number of protein-bound pigment molecules) is to absorb photons and transfer their energy to the reaction center. Simply saying, antenna pigments are light-harvesting complexes. They are composed of polypeptides, that bind chlorophyll a, chlorophyll b, carotene and xanthophylls.

Explanation:
Gregor Mendel knew how to keep things simple. In Mendel's work on pea plants, each gene came in just two different versions, or alleles, and these alleles had a nice, clear-cut dominance relationship (with the dominant allele fully overriding the recessive allele to determine the plant's appearance
