However, because of backward compatibility reasons in IOS and VTP, these VLAN numbers remain reserved and can not be used.

B and C are right

I always see 0 as a default but I mix it up with priority. Its a bit of a trick question to watch for

BC is correct .....VLAN 1 is a system default VLAN, you can use this VLAN but you cannot delete it. By default VLAN 1 is use for every port on the switch. Standard VLAN range from 1002-1005 it’s Cisco default for FDDI and Token Ring. You cannot delete VLANs 1002-1005. mostly we don’t use VLAN in this range
