The option used to specify the socket file pathname is . . . . . . . .

Solution (By Examveda Team)

This question asks about the command-line option used to tell MySQL where to find the socket file. A socket file is like a special address that MySQL uses to communicate with applications on your computer.

Let's break down the options:

Option A: -socket - This is the correct option! It's the standard way to specify the socket file's location. You'd use it like this: mysql -h localhost -u username -p -socket=/path/to/socket/file

Option B: -pathtosocket - This isn't a valid option.

Option C: -path_socket - This isn't a valid option either.

Option D: -socket_pathfile - While this might sound like it could be right, it's not a standard MySQL command-line option.

So, the answer is Option A: -socket.
