Which of the following chemicals/gases is/are responsible for causing the greenhouse effect?

Correct option is B

Water vapour, CO2 and CFCs are responsible for causing the greenhouse effect
· The greenhouse effect is primarily caused by certain gases in the Earth's atmosphere that trap heat from the sun, leading to an increase in the Earth's surface temperature. These gases are called greenhouse gases.
· Carbon dioxide (CO2): Released primarily from burning fossil fuels such as coal, oil, and natural gas, as well as deforestation and certain industrial processes.
· Water vapor: Although it is the most abundant greenhouse gas in the atmosphere, its concentration is largely influenced by other factors such as temperature and weather patterns.
· Chlorofluorocarbons (CFCs): Synthetic compounds used in refrigeration, air conditioning, and aerosol propellants.
