deactivates cylinders when operating under cruise or coasting conditions to save fuel.\n a. power - on…

Brief Explanations:

• Power - on - demand: This term is more related to providing power as per immediate requirements in a general sense and not specifically about cylinder deactivation for fuel - saving in the context of engine operation.
• Power splitting: Refers to distributing power between different components (e.g., in hybrid vehicles between engine and electric motor) rather than deactivating cylinders.
• Displacement - on - demand: This technology is designed to deactivate cylinders when the vehicle is operating under light - load conditions (such as cruise or coasting) to reduce fuel consumption. It adjusts the effective displacement of the engine by shutting down some cylinders.
• Regenerative braking: Captures energy during braking and stores it (e.g., in a battery) for later use. It has no relation to cylinder deactivation.

Answer:

C. Displacement - on - demand
