Chloroplast movement is widespread among algae, mosses, and leaves of higher plants, what will be the orientation of chloroplast in dark as well as in light?

a.) In dark, chloroplasts gather at the cell surfaces parallel to the plane of the leaf so that they are aligned perpendicularly to the incident light

b.) Under high light, , the chloroplasts move to the cell surfaces that are parallel to the incident light, thus avoiding excess absorption of light

c.) the orientation of the chloroplasts in the dark is such that maximizes absorption of light

d.) the orientation of the chloroplasts in the high light is such that maximizes absorption of light
