Best answer
The correct choice is (c) more, pg

The explanation is: The man command displays its output one page at a time. This is possible because it sends its output to a pager program. more pager is extensively used in UNIX system and it has replaced the original pager of UNIX i.e. pg. The task of a pager program is to simply display pages on the terminal. It can also be used to display the contents of a file.
