What is the most likely cause of this error?

After rebooting the host, you attempt to start the mysqld service.

You get the following error:Can’t start the server: Bind on TCP/IP port: Address already in use

What is the most likely cause of this error?
A . The mysqld service has already been started on the same port.
B . The network service process in the server is frozen, so all TCP/IP connections are paused and cannot be reused.
C . You failed to specify the port number 3306 to the command to start the server, so it is defaulting to port 80, which is in use by the built-in web server.
D . The /etc/hosts file does not have a valid IP entry for mysqld localhost, so it is binding to 127.0.0.1, which is already in use.
E . The mysql.sock file in the MySQL /tmp directory was not removed after the reboot, so mysqld still thinks there is an active server running.
