Correct choice is (b) Control volume

Easy explanation: In thermodynamics, an open system freely exchanges matter and energy with its surroundings. For instance, when you are boiling water in an open bowl on a stove, energy and matter are being transferred to the surroundings through steam. In this case, the volume remains constant making it a control volume process.
