Which of the following is a utility that can function as an independent spell checker?

A.
spell

B.
nice

C.
aspell

D.
inspell

Explanation:

aspell is a utility that can function as an ispell -a replacement, as an independent spell checker, as
a test utility to test out Aspell features, and as a utility for managing dictionaries.
Syntax:
aspell [options]
Some important options used with aspell are as follows:

Answer option B is incorrect. The nice command is used to change the priority of a process in the
kernel’s scheduler. A niceness of -20 is the highest priority and 19 is the lowest priority. The
default niceness for processes is inherited from its parent process, usually 0. For example, when
specifying a very low priority, the following command can be entered: nice -n 19 cc -c *.c &
The above command runs the cc command in the background at a lower priority than the default
priority set by the nice command.

Answer options D and A are incorrect. There are no such spell checkers as inspell and spell.
