Selected Answer: C
This is NOT a limitation. You can purchase and use Reserved Instances with dedicated tenancy. AWS allows you to purchase dedicated Reserved Instances to help reduce costs when using dedicated instances for longer terms.

It seems a questionable question. Only D is a valid statement within the answers, and it seems not related to any limitation.

A. All instances launched with this VPC will always be dedicated instances and the user cannot use a default tenancy model for them. -False, unless you flag the VPC as "Dedicated", which this question might be asking in a poorly worded fashion. B. It does not support the AWS RDS with a dedicated tenancy VPC. - Possibly. RDS can support Dedicated but the EC2 instance type has to be compatible. C. The user cannot use Reserved Instances with a dedicated tenancy model.- False, you can use Dedicated RI. D. The EBS volume will not be on the same tenant hardware as the EC2 instance though the user has configured dedicated tenancy. -This is a true statement
