Solution
The correct option is D Both assertion and reason are false
The greenhouse effect is the naturally occuring phenomenon that is responsible for heating of Earth's surface and atmosphere. Increase in the level of green house gases like carbondioxide, methane and CFCs has led to considerable heating of Earth leading to global warming.
UV ray is responsible for both formation and degradation of ozone in the stratosphere. But there should be a balance. CFCs disrupt this balance by enhancing ozone degradation.
