Answer:
C) Infrared is the correct answer.
Step-by-step explanation:
The greenhouse effect is a result of the Sun's energy being absorbed by objects on the Earth and converted into Infrared radiation.
The greenhouse effect is caused due to the increase in the level of gases such as methane, carbon dioxide in the atmosphere and when the greenhouse gases present in the air that trap the heat from the Sun,the temperature of the Earth's surface gets increase.
The greenhouses gases act as a blanket and it absorbs infrared radiation, this results in gradual heating of the earth's surface.
