Which statement about the greenhouse effect and greenhouse gases is correct?

A

Greenhouse gases absorb incoming short-wavelength solar radiation and reflect it directly back to space.

B

The greenhouse effect occurs because greenhouse gases absorb outgoing infrared radiation and re-emit it in all directions, including back towards Earth.

C

Decreasing the concentration of greenhouse gases in the atmosphere would cause the global average temperature to rise.

D

Diatomic nitrogen (N2\text{N}_2N2​) and oxygen (O2\text{O}_2O2​) are the primary greenhouse gases in Earth's atmosphere.
