False
Entropy change of adiabatic reversible process then only entropy change is zero because there will not be any entropy generation in the process
If it is adiabatic irreversible process then there will be entropy generation in this process. It contributes to the entropy change so entropy change is positive for adiabatic irreversible process

(a) A gas undergoes an irreversible adiabatic expansion. Is the entropy change of the gas + environment the same as for a reversible process that leads to the same final state for the gas+environment? Choices: smaller, larger, the same, or it depends (b) A gas undergoes a cycle described on a PV diagram. For a complete cycle, the entropy change of the gas and environment are: Choices: positive for the environment but not necessarily zero for the gas, zero, negative,...
