It's A: VNET 3 and 4 only. All the IP's for the ranges 10.11.0.1 - 10.11.255.254 VNET1 10.11.0.1 - 10.11.127.254 VNET2 10.10.0.1 - 10.10.3.254 VNET3 192.168.16.0/22 VNET4 - not even same class VNET 2 is out. Others are OK. If you're not strong with subnetting just remember the lower the number the more addresses. So a /16 will include all the address of /17, /18, 19... and so on up to /30. /16 is also the just the last 2 octets. That is why 10.10.0.0 is ok.
