Explanation

Creating a virtual switch within the hypervisor establishes an internal-only network that is visible solely to the virtual machines on that hypervisor. It does not connect to any physical network interface and therefore is not routable to the firewall or beyond. Creating a VLAN without a default gateway (A) would still use physical infrastructure. Removing a route from the routing table (B) is a workaround that does not truly isolate the network. A stand-alone physical switch (D) defeats the purpose of keeping everything virtual and isolated within the hypervisor.
