ACarotenoids with carotene molecules
BXanthophyll yellow pigments only

DChlorophyll b with extra methyl group
Answer & Solution
Correct answer: C. Chlorophyll a with magnesium centre
Chlorophyll a is the principal photosynthetic pigment. It exists as P680 in PS II and P700 in PS I reaction centres. Other pigments (chl b, xanthophyll, carotenoids) are accessory pigments that funnel energy to chl a.
