    A is correct.

    Troubleshooting VXLAN Installation in NSX for vSphere 6.x (2124894)
    https://kb.vmware.com/s/article/2124894

    Quoted from above link.
    Run this command to verify the MTU is configured to 1600 or above:

    # ping ++netstack=vxlan -d -s 1572 -I vmkx hostname_or_IP

    Where vmkx is the ID of your vmkernel port and where hostname_or_IP is the IP or hostname of your vmkernel port.

    This allows you to check the validity of all uplinks. If you are working in a multi-VTEP environment you can validate all uplinks by running a ping from each possible VTEP vmkernel source/destination interface to validate all paths.

    For more information about this MTU check, see the Verify the NSX Working State section in the NSX 6.2 Upgrade Guide.
