Question

• A. Oil

• C. Nuclear energy
• D. Other organic substance

Answer 1

The correct option is C Nuclear energy

The processes for which any CO2 is not evolved is :

• all the forms of nuclear energy,

• hydroelectricity (though dam reservoirs in the tropics might free a little methane, which is a greenhouse gas, because of the decaying of biological debris in the water),

• sun rays,

• wind,

• tidal energy,

• geothermal energy,

• biomass if replanted.
• So the correct option is C.
