Which of the following commands shows the absolute path to the current working directory?

`who` displays information about users currently logged into the system, not the current directory path.

`cd ..` changes the current working directory to the parent directory; it does not display any path.

`pwd` stands for 'print working directory' and always outputs the full absolute path from the filesystem root (e.g., /home/user/documents). It takes no arguments for basic use and is a POSIX-standard utility available on all Linux systems.

`ls -l` lists the contents of the current directory in long format but does not print the directory's own absolute path.

`cd ~/home` attempts to change the working directory to a subdirectory called 'home' inside the user's home directory; it does not display a path.
