Correct Answer: A
The Hardware Abstraction Layer (HAL) is implemented in the system software. The system software is the software that controls and manages the basic operations and functions of the computer system, such as the operating system, the device drivers, the firmware, and the BIOS. The HAL is a component of the system software that provides a common interface between the hardware and the software layers of the system. The HAL abstracts the details and differences of the hardware devices and components, and allows the software to interact with the hardware in a consistent and uniform way. The HAL also enables the system to support multiple hardware platforms and configurations without requiring changes in the software5 . References: 5:
