• C. additional heat entrapment
• D. all of these

Answer 1

Answer: (A), (B), (C)

The correct options are
A carbon dioxide gas
B other green house gases
C additional heat entrapment

The main cause of global warming is the excess of greenhouse gases in the atmosphere. Carbon dioxide is the major greenhouse gas. Apart from this, there are many greenhouse gases such as methane or biogas, nitric oxide - released from vehicles and jet planes, etc. Hence, to reduce global warming, we must reduce the emission of greenhouse gases into the atmosphere.
