B.

C.

D.
None, EIGRP and IGRP are automatically redistributed in this instance.
Answer: D
Explanation
If IGRP and EIGRP use the same Autonomous System (AS) then redistribution occurs automatically. In this case both IGRP & EIGRP use the same AS 123 so they are automatically redistributed.
If IGRP and EIGRP use different AS numbers then redistribution must be done manually.
