Solution
The correct answer is "IOException is thrown when opening the socket".
Here's why: In Java, when a ServerSocket is not able to listen on a specified port (because the port is already in use or it's a restricted port and the process doesn't have the necessary permissions), an IOException is thrown. This is a checked exception that signals some sort of input or output issue, in this case, the inability to open a socket on the specified port. The system will not wait until the port is free, it will not exit gracefully with an appropriate message, and there is no such thing as a PortOccupiedException in Java.
