Solution
The correct option is A ATP and NADPH.
The main photosynthetic pigment chlorophyll a and accessory pigments chl. b, chl. c and carotenoids etc., trap the sunlight to carry out the light reactions of photosynthesis. The light reaction of photosynthesis produces ATP and NADPH which in turn serve as the energy source to drive the second phase of photosynthesis (dark reactions) during which carbohydrate synthesis takes place.
