Which clause specifies periodic execution at fixed intervals?

This question is about how to set up tasks in MySQL that run automatically at specific times.
The options are different ways to describe the timing of these tasks:
Option A: EVERY - This is the correct answer! It's used to define tasks that happen repeatedly at fixed intervals. For example, "EVERY 10 minutes" or "EVERY hour".
Option B: ALL - This is not used for specifying intervals in MySQL.
Option C: AT - This is used for scheduling tasks to run at a specific point in time, like "AT 10:00 AM".
Option D: ALTERNATE - This is not used for scheduling tasks in MySQL.
So, if you want a task to run regularly, you'd use the "EVERY" clause to set the time between executions.
