Refer to the exhibit. EIGRP had converged in AS 1 when the link between router R1 and R2 went down. The console on router R2 generated the following messages:
*Mar 20 12:12:06: %DUAL - 5NBRCHANG E: IP - EIGRP 1: Neighbor 10.1.4.3 (Serial0) is down: stuck in active
*Mar 20 12:15:23: %DUAL -3- SIA: Route 10.1.1.0/24 stuck - in - active state in IP - EIGRP 1.

C. Router R3 did not reply to the query about network 10.1.1.0/24 sent by router R2 .
D. Router R5 did not reply to the query about network 10.1.1.0/24 sent by router R2 .
