Greenhouse gases absorb radiation energy mostly in which of the following regions of the solar spectrum?

Greenhouse gases absorb most strongly in the infra-red region, trapping the long wave heat that the Earth radiates back to space.

X-ray energy is far too high in frequency and is filtered high in the atmosphere, not by greenhouse gases near the surface.

Ultraviolet radiation is chiefly absorbed by the ozone layer, not by greenhouse gases warming the lower atmosphere.

Visible light largely passes straight through the atmosphere to reach and warm the ground.

The Earth absorbs incoming sunlight and re-emits it as infra-red, which the greenhouse gases then capture.

Carbon dioxide, methane, water vapour and nitrous oxide are the main infra-red absorbing gases.
