How must the services be stabilized?

Refer to the exhibit.

Routing protocols are mutually redistributed on R3 and R1. Users report intermittent connectivity to services hosted on the 10.1.1.0/24 prefix. Significant routing update changes are noticed on R3 when the show ip route profile command is run.

How must the services be stabilized?
A . The issue with using BGP must be resolved by using another protocol and redistributing it into EIGRP on R3
B . The routing loop must be fixed by reducing the admin distance of iBGP from 200 to 100 on R3
C . The routing loop must be fixed by reducing the admin distance of OSPF from 110 to 80 on R3
D . The issue with using iBGP must be fixed by running eBGP between R3 and R4

Answer: B
