The database security group allows port 5432 from the app tier's subnet CIDR 10.0.1.0/24. A new batch server is placed in that subnet. What better rule limits access to app servers only?

A.Allow 5432 from the app tier's security group ID as the sourceB.Allow 5432 from 10.0.0.0/16 so the rule covers all subnetsC.Allow 5432 from 0.0.0.0/0 and rely on the database passwordD.Remove the rule and use a network ACL deny for the batch server
