How many options can be used with pwd command

I would like to know that how may options can be used with pwd command on Linux?

Not many. Only two on GNU/Linux. Typically you just run:

pwd
pwd -P
pwd -L

You can read man page by typing the following:

man pwd
pwd --help

Sample outputs:

pwd: pwd [-LP]
    Print the name of the current working directory.
    
    Options:
      -L	print the value of $PWD if it names the current working
    		directory
      -P	print the physical directory, without any symbolic links
    
    By default, `pwd' behaves as if `-L' were specified.
    
    Exit Status:
    Returns 0 unless an invalid option is given or the current directory
    cannot be read.
