  answer D: Spread works only in 1 region. Max instace per avalibility zone 7. if 3 availibility zone = 21 Istance. ( Question=10 istance) "A spread placement group is a group of instances that are each placed on distinct racks, with each rack having its own network and power source." All istance are placed on different racks for a maximun of 7 istance for Availability Zone. "A spread placement group can span multiple Availability Zones in the same Region. You can have a maximum of seven running instances per Availability Zone per group." https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/placement-groups.html#placement-groups-spread
