    A and D are correct.
    B=multiple VMs on same hosts, we don’t have to use Physical NIC. They use internal virtual wire and virtual switch to communicate each other.

    C=Trunk Port is function on Physical switch. not related vSphere.

    A, D
    The vSwitch uses the physical NICs (pNICs) associated with the host server to connect the virtual network to the physical network. In VMware, these pNICs are also called uplink adapters. Uplink adapters use virtual objects called vmnics, or virtual network adapters, to interface with the vSwitch.

    Once the vSwitch has bridged the connection between the virtual network and the physical network, the virtual machines residing on the host server can begin transferring data to, and receiving data from, all of the network-capable devices connected to the physical network. That is to say, the virtual machines are no longer limited to communicating solely across the virtual network.
