With over 62 hosts in each VLAN, the subnet size for each must be at least /25 which is the same as 255.255.255.128 (B). So the range of VLAN 1 is 172.16.1.0 to 172.16.1.127, and for VLAN 2 it is 172.16.1.128 to 172.16.1.255. This puts the IP address 172.16.1.25 into VLAN 1 (C). The router needs an IP address from each VLAN so it can route packets between them (F).
