Solution

The correct option is B Both A and R are true but R is not the correct explanation of A

A greenhouse allows the sunlight to pass through. It traps the heat inside and does not allow the heat to escape out.

CO2 in the troposphere behaves like glass panels of a greenhouse allowing the sunlight to pass through, but preventing the heat from being re-radiated into outer space.

During day time, Earth's surface warms up and at night, Earth's surface cools down, releasing the heat back into the air.

But, some of the heat is trapped by the greenhouse gases (especially carbon dioxide and water vapour). This prevent the heat from escaping into outer space.
