The correct answer is:
If both assertion and reason are true and reason is the correct explanation of assertion
In an irreversible process, there always occurs some loss of energy. This is because energy spent in working against the dissipative force is not recovered back. Some irreversible processes occur in nature such as friction where extra work is needed to cancel the effect of friction. Salt dissolves in water but a salt does not separate by itself into pure salt and pure water.
