Why each option

Host-only networking isolates the VM to communicate exclusively with the host workstation, matching the described behavior where the VM cannot reach any external network.

AHost-onlyCorrect

Host-only networking creates a private virtual network adapter that connects only the VM and the host machine, with no routing to any physical network or the internet. This is the configuration that results in the VM being reachable solely from the local workstation, which exactly matches the described scenario where the VM 'can only connect to the local workstation'.

BBridged

Bridged networking connects the VM directly to the same physical network as the host, assigning the VM its own IP on the LAN and granting it full external network access - not just the workstation.

CNAT

NAT networking allows the VM to reach external networks and the internet by sharing the host's IP address, so it is not limited to communicating with only the local workstation.

DDual-homed

Dual-homed describes a host or router configured with two separate network interfaces connected to two different networks, and is not a virtual machine network mode.
