Which command is used for taking "server side help" in Mysql command line tool?

This question is asking about a command used in the MySQL command-line tool to get help directly from the server.
Think of it like asking the MySQL server, "Hey, can you give me some information?"
Let's look at the options:
Option A: /h - This is the correct command to get server-side help in MySQL. It's like asking the server for a quick reference guide.
Option B: /c - This command is used for clearing the screen. It's not related to getting help.
Option C: /e - This command is used to exit the MySQL command line tool. It's not for getting help.
Option D: None of the mentioned - This is incorrect because option A, /h, is the correct answer.
So the answer is Option A: /h.
