shortcut

B.
ln

C.
sudo

D.
link

E.
alias

Explanation:
In bash you can use alias to create shell internal commands.
Example:
$ alias
alias grep=’grep –color=auto’
alias ll=’ls -alF’
alias ls=’ls –color=auto’
ln creates symlinks or hardlinks (can be used to create aliases, but does not work with options)
sudo starts a command with root privileges
