B is the correct answer which is carbon dioxide and methane
B. Carbon Dioxide And Methane
Greenhouse gases include carbon dioxide, methane, nitrous oxide and other gases that accumulate in the atmosphere and create the heat-reflective layer that keeps the Earth at a livable temperature.
carbon dioxide and methane
Greenhouse gases mean they greatly contribute to the greenhouse effect which means they cause the atmosphere to retain most of the heat reflect back from the earth's surface from the sun with mottle escaping back to space. This causes the earth to warm.
Methane is even more potent than carbon dioxide as a greenhouse gas (about 30 times). The greenhouse gases have a knack for absorbing thermal infrared waves due to their molecular and vibrational spectrum. When the sun rays heat up the earth surface, it releases heat back most if which is in infrared range. Most should escape back to space. However, an atmosphere with higher greenhouse gases will have them absorbed and then releases back to earth and in other directions of the atmosphere. This causes the atmosphere to become warmer hence the phenomenon called global warming.

Correct B). Carbon dioxide and methane
Greenhouse gases are those gas which traps the heat of the atmosphere, it absorbs the heat energy and allows the less heat to escape back to space.
The greenhouse gases found naturally in the earth's atmosphere are carbon dioxide, water vapor, methane, and nitrous oxide, while the man made greenhouse gases are Chlorofluorocarbons, hydrofluorocarbons etc.
The concentration of these both the greenhouse gases are increasing rapidly due to industrialization and overuse of fossil fuel such as coal, petroleum etc which ultimately leads to global warming.
But the most common gases know are Carbon dioxide and Methane.

the types of mutations include: missense mutation: this type of mutation is a change in one dna base pair that results in the substitution of one amino acid for another in the protein made by a gene. nonsense mutation: a nonsense mutation is also a change in one dna base pair.
