Option D's description of /etc/profile is fictitious (it applies to /etc/passwd ), but its description of /etc/bashrc is correct. |

Answer : [A]
Explanation :
Explanation :
| The /etc/rc.d/rc3.d is one of several possible locations for links to SysV startup scripts that are to be run when entering runlevel 3. Because this link name begins with S , this link causes the service to be started when entering runlevel 3, so option A is correct. This location is not used to point servers to configuration files or to run servers via the inetd super server, so options B and C are incorrect. When a SysV startup script is launched without options, it displays an error message, so option D is incorrect. |
