Which best explains why people see carrots as orange? a) the carrots reflect only orange light. b) the carrots absorb orange light from the sun. c) orange light changes direction when it hits the carrots. d) the carrots are opaque and do not allow orange light through.

Option A

Explanation:

Carrots are composed by a large proportion of carotenoids. These are pigments that can absorb most of the light spectrum, peaking between 450-550nm, and falling at the yellow-orange range which is around 600nm and above. Therefore, the yellow-orange light that is not absorbed reflects towards our eyes.
