300-410 ENARSI: Implementing Cisco Enterprise Advanced Routing and ServicesDemo

Booking traffic (to the Hotel server behind R2) works, but payment traffic to the Bank server 192.168.94.0/24 behind R1 fails, so the problem is specific to reaching R1's networks from R3. R1's router LSA correctly advertises 192.168.94.0/24 into OSPF, so R3 should learn it via OSPF (AD 110). However the 'show ip route' output reveals R3 is using a static route (AD 1) whose next hop 172.16.1.26 points back into PC1's own LAN - a black hole - and that lower-AD static overrides the good OSPF path. Raising the administrative distance of the offending static route toward the bank network to 200 (choice A) lets the OSPF route win and restores the correct path, fixing payment. Options C (OSPF AD is already better than a floating static once the static is raised) and D/B do not address the static-vs-OSPF preference that the exhibit highlights. Community discussion is split between A and B; A best matches the static-override evidence shown.
