Explanation

If for any reason VM crashes autoscaling set as OFF wont spin another instance in its place which would defeat the purpose of always running VM(tough there will be some disruption) as -- Max-num-Instance is set to 1. There is no mention of auto-healing is set or not which is disable by default. B - Incorrect - Does not fit the requirement because AFTER the deletion of the instance, no other instance was created.
