    would someone explain why C is correct?

    The destination IP address 10.1.5.65 belongs to 10.1.5.64/28, 10.1.5.64/29 & 10.1.5.64/27 subnets but the “longest prefix match” algorithm will choose the most specific subnet mask -> the prefix “/29″ will be chosen to route the packet. Therefore the next-hop should be 10.1.3.3 -> C is correct.

    @drvyn

    C is correct. The router it will chose the most specific mach recorded in it’s routing table. After AND-ing, the right interface it will be s0 (29 bits matching)
