Solution
The correct option is B PS II
Since light wavelengths have been categorized into two groups. So the pigments affected by them are also divided into two; that is PS I and PS II. PS- I comprise p - 680, chlorophyll a -695, p-700 and chlorophyll- b and carotenoids whereas PS- II consists of chlorophyll a 670, chlorophyll a-690, chlorophyll b and phycobilin and therefore light is absorbed in PS - I at 700 and in PS - II at or just below 680. If wavelength used is beyond 680 nm ps II will not function, as this happens in the region of red light, it is called red drop phenomenon.
