How is a stored procedure invoked?

Answer: Option C

Solution:

This question is asking about how you "run" or "execute" a stored procedure in MySQL. Stored procedures are like little programs that you write to perform specific tasks in your database.

Here's the breakdown of the options:

Option A: INVOKE
While "INVOKE" is a keyword used in some database systems, it's not the standard way to call a stored procedure in MySQL.

Option B: SEE
"SEE" is not a valid command in MySQL for running stored procedures.

Option C: CALL
This is the correct answer! You use the CALL keyword followed by the name of your stored procedure to execute it.

Option D: RETURN
"RETURN" is used inside a stored procedure to send back a value. It's not how you initiate the procedure itself.

In summary: The right way to invoke (or run) a stored procedure in MySQL is with the CALL command.
