The correct option is D Kernel approach
UNIX operating system
is based on kernel approach.
In a monolithic
kernel, all OS services run along
with the main kernel thread, thus also residing in the same memory area. This
approach provides rich and powerful hardware access. Some developers, such as
UNIX developer Ken Thompson, maintain that it is "easier to implement a
monolithic kernel" than micro kernels.
The kernel is the essential center of a computer operating system (OS). A kernel is often contrasted with a shell,
which is the outermost part of an OS that
interacts with user commands. Kernel and shell are terms used more
frequently in UNIX.
A kernel is the central part of an operating system. It manages the operations of the computer and
the hardware - most notably memory and CPU time.
