Answer:
The correct option is: carbon dioxide, methane, water vapor.
Step-by-step explanation:
Greenhouse gases, such as carbon dioxide (CO2), methane (CH4), and water vapor (H2O), trap heat in the Earth's atmosphere, leading to the greenhouse effect and global warming. Water vapor is the most abundant greenhouse gas, while carbon dioxide and methane also play significant roles. Carbon dioxide is released through activities like burning fossil fuels, deforestation, and industrial processes. Methane is produced by sources such as agriculture, natural gas production, and organic waste decay. Other gases like oxygen, argon, nitrogen, and helium do not significantly contribute to the greenhouse effect.
