I dunno the exact way for deleting a particular command from history but if you want to CLEAR all the commands from HISTORY then use :

clear history

Hope this helps !

Yes they are stored in .bash_history and if you delete them from the file but obvious it 's not going to affect your current history coz those are stored in the Env Variable.

Have tried :

# history -d <line number>

This should work !

Thank you in advance.

Are you looking for roots .bash_history or the users one? The users one is in /home/username/.bash_history.
