Answer C https://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/consolidatedbilling-other.html "For an Amazon EC2 Reserved Instances example, suppose that Bob and Susan each have an account in an organization. Susan has five Reserved Instances of the same type, and Bob has none. During one particular hour, Susan uses three instances and Bob uses six, for a total of nine instances on the organization's consolidated bill. AWS bills five instances as Reserved Instances, and the remaining four instances as regular instances."

Answer is D actually. Account A and Account B are both charged as RIs for all of their instances, because the RIs are scoped to a Region, not to an Availability Zone. This means that the RIs can be applied to any matching usage within the same Region, regardless of the Availability Zone or the account. Therefore, the five RIs purchased by Account A are enough to cover the eight instances running by both accounts, as long as they match the attributes of the RIs.
