Correct Option (d)
Reason : Solar energy is not responsible for green-house effect instead it is a source of energy for the plants and animals. Green plants prepare their food by the use of this solar energy. CO₂ gas is mainly responsible for greenhouse effect. Excess of this gas forms a thick layer around the earth and prevents re-radiation of earth climate entering sun rays to atmosphere. Thus, functions like the glass pannels of a green house (or the glass windows of a motor car). This is thus, called greenhouse effect.
