Option 1 : 1 and 2

Explanation:

Free expansion of a gas is an irreversible process in thermodynamics in which a volume of a gas is kept in one side of a thermally isolated container with the other side of the container being evacuated. Hence it highly irreversible process
Slow heating is not the sole condition of being reversible; we also need to focus on temperature difference.
Evaporation is a reversible physical reaction. The reverse process is water condensing from the atmosphere onto a surface. Evaporation involves the change in state from liquid to gas.
Isentropic compression of an ideal gas is a reversible process.
