The correct answer is:

(c) Both a and b

A system that is not in steady state is in a state where conditions such as temperature, pressure, or concentration are changing with time. This state can be described as both transient state and unsteady state, as both terms refer to the system being out of equilibrium and undergoing changes over time.
