A policy needs to be implemented on Router B so that any traffic sourced from 172.16.10.0/24 will be forwarded to Router C. Which configuration on Router B will achieve the desired effect?（）

A.access - list 1 permit 172.16.10.0 0.0.0.255  !  interface e0  ip policy route - map policy  !  route - map policy permit 10  match ip address 1  set ip next - hop 1 72.16.14.4
B.access - list 1 permit 172.16.10.0 0.0.0.255  !  interface s0  ip policy route - map policy  !  route - map policy permit 10  match ip address 1  set ip next - hop 172.16.12.3
C.access - list 1 permit 172.16.10.0 0.0.0.255  !  interface e0  ip polic y route - map policy  !  route - map policy permit 10  match ip address 1  set ip next - hop 172.16.12.2
D.access -list 1 deny 172.16.10.0 0.0.0.255  !  interface s0  ip policy route - map policy  !  route - map policy permit 10  match ip address 1  set ip next - hop 172.16.12.2
