A router receives a packet on interface 172.16.45.66／26. The source IP of the packet is 172.16.45.127／26 and the destination is 172.16.46.191／26.How will the router handle the packet?()
A. The destination is a host on another subnet, so the router will not forward the packet.B. The destination is a host on the same subnet, so the router will forward the packet.C. The destination is a broadcast address, so the router will not forward the packet.D. The destination is a network address, so the router will forward the packet.
