Solution
The correct option is C Less than the present level The carbon dioxide is one of the green house gases. These gases are capable of capturing and trapping the heat in the earth's atmosphere which helps to maintain the balance of heat in the atmosphere. If there is no carbon dioxide in the atmosphere, the heat would escape easily from the atmosphere. The temperature of the earth would be much lower than the present temperature.
