Consider this Celery Beat schedule configuration in a Flask app:

app.config['beat_schedule'] = {
  'notify': {
    'task': 'notifications.send_email',
    'schedule': 10
  }
}

What will Celery Beat do when running with this setup?

ARun the task only once at app startup

BExecute the 'notifications.send_email' task immediately once

CIgnore the task because 'schedule' must be a crontab object

DSend the 'notifications.send_email' task to workers every 10 seconds
