However， the configurationis incorrect. On the basis of the information in the exhibit， which configuration option wouldcorrectly configure router NET？（）
A.The first three statements of ACL 112 should have permitted the ICMP traffic and the laststatement should deny the identified traffic
B.The last statement of ACL 112 should have been "access-list 112deny icmp any 10.2.1.00.0.0.255"
C.The last statement of ACL 112 should have been "access-list 112permit icmp any 10.2.1.00.0.0.255"
D.ACL 112 should have been applied to interface Fa0/0 in an inbound direction
E.The last statement of ACL 112 should have been "access-list 112deny icmp any 10.1.1.00.0.0.255"
F.ACL 112 should have been applied to interface Fa0/1 in an outbound direction
