Best answer
Right answer is (c) passwd

For explanation I would say: Since UNIX is a multiuser system, it requires a password from every user who wants to log in to the system to help ensure that all the data and files of the user are secure from hackers and errant users. A user can simply change his/her login password by using the passwd command. Simply type this command on the terminal and then enter the old password, which after successful verification would allow the user to input a new password for his login.
