Carbon dioxide is called greenhouse gas because it is:
- Atransparent to sunlight but traps heat.
- Btransparent to heat but traps sunlight.
- Cused in greenhouse to increase plant growth.
- Dtransparent to both sunlight and heat.
Solution & Step-by-step Explanation
Carbon dioxide () is categorized as a greenhouse gas because it is transparent to incoming short-wave solar radiation (sunlight) but efficiently absorbs and traps outgoing long-wave infrared radiation (heat) re-radiated from the Earth's surface, leading to the warming of the atmosphere.
