Select the best response.

A.
R1 will permit only the 10.0.0.0/24 route in the R2RIP updates

B.
R1 will not filter any routes because there is no exact prefix match

C.
R1 will filter the 10.1.0.0/24 and the 172.24.1.0/24 routes from the R2 RIP updates

D.
R1 will filter only the 172.24.1.0/24 route from the R2 RIP updates

Explanation:
The command “distribute-list 10 in Serial0″will create an incoming distribute list for interface
serial 0 and refers to access list 10. So it will permit routing updates from 10.0.x.x network
while other entries (in this case the 10.1.0.0/24 and 172.24.1.0/24 networks) will be filtered
out from the routing update received on interface S0.
