Friction is Main causes of irreversibility.

Reversible is a closed process there will be no heat loss and can reach to the final position where as in irreversible process it cannot reach to its final position as it is open process and heat loss occurs.

Irreversible is a isentropic process so in this process is heat loss.

In irreversible process heat is generated by friction. So answer is A.

Irreversible is adiabatic process.

If any process is done there may be loss of energy (heat). Such that in irreversible process heat is released & we cannot collect it. Hence in irreversible process heat is loss.

In reversible process heat can change in this process apple thermodynamic first law. Heat can not created or not destroyed when any process go reversible this heat chang due to some friction and some surrounding loss heat.

It is not always true. Ex- let us consider an insulated container (system) having two gases with a finite pressure difference separated by a partition. Removing the partition will result in an irreversible process due to finite pressure difference.
But in this case there is no heat transfer as the system is insulated. So, an irreversible process not necessarily result in heat loss.

Amount of heat loss is proportional to irreversibility.

Irreversible process is always accompanied by the increase in entropy.
