Assuming that the routing protocol for this network is EIGRP, if the link between R1 and R3 failed,
what would R4 receive from R3?

A.
R4 would receive an update noting R3’s higher cost to reach 172.30.1.0/24.

B.
R4 would not receive any updates or queries, since R3 would simply move to the path through
R2.

C.
R4 would receive a query, since R3 would mark 172.30.1.0/24 as active when the link between
R1 and R4 failed.

D.
R4 would not receive any packets, since R3 is not using the link to R1 to reach 172.30.1.0/24.
