D Correct answer
Explanation

An isothermal process is one where temperature remains constant throughout. In thermodynamics, different prefixes indicate different constant conditions: iso-same, thermal-temperature (isothermal), baric-pressure (isobaric), choric-volume (isochoric). Adiabatic means no heat exchange, not constant temperature.
