The design must influence how EIGRP-learned routes are injected into the OSPF domain, so R2 should redistribute EIGRP into OSPF as metric-type E1 and R3 as metric-type E2. Cisco OSPF documentation distinguishes external Type 1 and Type 2 routes. An E1 route includes the external cost plus the internal OSPF cost to reach the ASBR, while an E2 route uses only the external metric. Cisco path selection prefers O E1 over O E2 for the same external destination. Therefore, making R2 advertise the EIGRP routes as E1 causes OSPF routers to prefer R2 as the exit toward the EIGRP domain. Option C adjusts OSPF-to-EIGRP redistribution, which is the wrong direction for traffic passing toward EIGRP from OSPF. Removing redistribution on R3 would reduce redundancy. Option D reverses the preference and would favor R3. Reference topics: OSPF external route types, EIGRP-to-OSPF redistribution, ASBR preference, E1 versus E2 metrics.
