A/An _______ is an interface between the user and hardware.

Correct option is D

The correct answer is option (D) Operating System

An operating system (OS) is the interface between the user and the hardware of a computer. It manages hardware resources, provides services for computer programs, and enables users to interact with the computer system through a user-friendly interface. The operating system facilitates the execution of applications, manages files, and handles input and output operations, effectively acting as a mediator between the hardware and the user. Popular examples of operating systems include Windows, macOS, Linux, and Android.
