　 Router (config-std-nacl) #permit any

B.Router (config) #ip access-list standard block

　Router (config-std-nacl) #permit any

　Router (config-std-nacl) #deny 10.0.0.0 0.255.255.255 log

　Router (config-std-nacl) #deny 172.16.0.0 0.15.255.255

C. Router (config) #ip access-list standard block

　 Router (config-std-nacl) #deny 172.16.0.0 255.240.0.0

　 Router (config-std-nacl) #permit any

D. Router (config) #ip access-list standard block
