In compliance with the FHS (Filesystem Hierarchy Standard), man pages are found in the '/usr/share/man' directory. Option A is the correct answer. The FHS is a standard that defines the directory structure and layout of a Linux or Unix-like operating system. It specifies the location of various types of files, including man pages. According to the FHS, man pages are documentation files that provide detailed information about system commands and utilities. They are usually accessed through the 'man' command, which displays the man page for a specified command or utility. In compliance with the FHS, man pages are stored in the '/usr/share/man' directory. This directory is divided into several subdirectories, each containing man pages for a specific section. For example, the '/usr/share/man/man1' directory contains man pages for executables in the '/usr/bin' directory, while the '/usr/share/man/man3' directory contains man pages for library functions in the '/usr/lib' directory.
