Which statement is used to produce a stored function?

This question is asking about how you create a stored function in MySQL. A stored function is like a mini-program that you can store in your database and call whenever you need it. It's a way to make your database code more organized and reusable.

Out of the options given, the correct answer is Option B: CREATE FUNCTION.

Let's break down the other options:

* Option A: PRODUCE FUNCTION - This is not a valid MySQL command.
* Option C: PRODUCE PROCEDURE - This is also not a valid MySQL command.
* Option D: CREATE PROCEDURE - This command is used to create a stored procedure, which is similar to a function, but doesn't return a value.

So, to create a stored function, you would use the CREATE FUNCTION statement.
