Selected Answer: C
- The on_failure_callback is a function that gets called when a task fails. - Assigning a function with notification logic to this parameter is a direct way to handle task failures. - When the task fails, this function can trigger a notification, making it an appropriate solution for the need to be alerted on task failures.
