Question

Which of the following gases is responsible for the greenhouse effect?

• A. Oxygen
• B. Carbon dioxide
• C. Nitrogen
• D. Hydrogen

Hint:

Greenhouse gases absorb infrared radiation and trap heat, contributing to global warming.

Answer 1

The Correct Option is B

Carbon dioxide (CO$_2$) is one of the major greenhouse gases responsible for trapping heat in the Earth's atmosphere, leading to the greenhouse effect. Other greenhouse gases include methane (CH$_4$), water vapor (H$_2$O), and nitrous oxide (N$_2$O). Thus, the correct answer is option (2).
