Explanation

In this scenario, routers C and D are EIGRP stub routers (circuit routers) connected to the edge of the network. Normally, stub routers do not advertise routes received from other EIGRP neighbors - they only advertise their connected or summary routes. However, the network needs router C or D to advertise the 10.0.4.0/24 prefix to protect against a failure between routers B and D. The 'stub leak-map' option allows an EIGRP stub router to selectively advertise specific routes (defined in a route-map) that would otherwise be suppressed by the stub configuration. This gives the design the protection of a stub (preventing suboptimal routing and query propagation) while still allowing targeted route advertisement for resilience. Stub connected (A) only advertises connected routes. Stub redistributed (B) advertises redistributed routes. Stub receive-only (C) advertises nothing - the most restrictive option and opposite of what is needed here.
