B. Some outgoing longwave (infrared) radiation is absorbed and re-emitted by atmospheric gases, warming the planet.
Explanation: Greenhouse gases (e.g., CO2, water vapor) are mostly transparent to incoming shortwave solar radiation but absorb and re-radiate infrared radiation emitted by Earth's surface, trapping heat and raising surface and lower-atmosphere temperatures. The other choices are incorrect for the reasons above.
