The /cat/etc/passwd file on a client computer contains the following entry: Martha:x:::::bin/false Which of the following is true for Martha?

The 'x' in the second field is a placeholder indicating the actual password hash is stored in /etc/shadow, not that the literal password is the character 'x'.

Full access would require a valid interactive shell and appropriate group permissions; /bin/false as the shell blocks login entirely before any access can be granted.

Limited access implies the user can log in but with reduced privileges; /bin/false prevents the login session from ever being established, which is denial rather than restriction.

The seventh colon-delimited field in /etc/passwd specifies the user's login shell. When set to /bin/false, every login attempt exits immediately with a failure status code, preventing Martha from establishing any session on the system. This technique is commonly used for service or system accounts that must exist in the user database but should never be used for direct interactive logins.
