If an opaque material appears to be green, then which of the following can be concluded?
All color frequencies of light are reflected, except for green which is absorbed.
All color frequencies of light are absorbed, except for green which is reflected.
All frequencies of light are reflected, but green is reflected at a different angle than all others.
Green is the only frequency of light that is absorbed.

B

Explanation:

If a light is reflected, that means that it bounces back from the material in the opposite direction. This means that we will be able to see that reflected color. Here, since we see green, we know that green has been reflected.

Meanwhile, if we don't see any color, then we know those colors are absorbed by the material.

Thus, the answer is B.
