Answer:
(C) Energy emitted by greenhouse gases.
Step-by-step explanation:
The heat that occurs due to the absorption of approaching shortwave radiation is discharged as longwave radiation. The fallout from the warmed upper environment, alongside a modest quantity from the Earth's surface, transmits out to space. A large portion of the discharged longwave radiation warms the lower climate, which thus warms our planet's surface.
Greenhouse gases in the air assimilate the more significant part of the Earth's produced longwave infrared radiation, which warms the lower climate.
