C. VMware Transit Connect
Explanation:
VMware Transit Connect provides high-speed, resilient connectivity and is integrated with the AWS Transit Gateway. With VMware Transit Connect, customers can connect their software-defined data center (SDDC) network, Amazon Virtual Private Clouds (VPCs), and on-premises data centers. This allows them to have a seamless networking connectivity between their VMware Cloud on AWS SDDC and their native AWS environment. So, for the given scenario where the customer wants to connect to both their on-premises data center and multiple VPCs in the same AWS region, VMware Transit Connect would be the most appropriate choice.
