Gases in the atmosphere absorb heat.

Explanation: Greenhouse gases (CO2, water vapor, methane, etc.) absorb outgoing infrared (longwave) radiation from Earth and re-radiate it, warming the lower atmosphere and surface. The other choices describe scattering or optical effects, not the greenhouse mechanism.
