Why do plants have more than one type of pigment in their leaves?

A) One set of pigments is active in the light-gathering phase of photosynthesis and another set makes the leaves appear green.
B) Certain pigments are active at different temperatures,making photosynthesis possible in warm and cool weather.
C) The various pigments respond to different wavelengths of light,allowing plants to absorb more of the available light.
D) Some of the pigments absorb light energy and others gather and process carbon dioxide into sugars.
E) Each pigment is active during a different time of day,giving the plant more time to photosynthesize.
