Answer
Essential features without knowing the background details
Reason — Data abstraction is defined as the act of representing only the essential features while hiding the background details. For example, when we drive a car, we use the steering wheel, accelerator, clutch, and brake. We are not concerned about how they are designed or how they work internally.
