D 5
Selected Answer: D
I would say the question describes the issue as the engineer intending to permit 10.0.0.0/8 networks, but only 10.0.0.0/8 is left and other specific subnets like 10.1.1.0/24 are missed. how to fix it.
then we can say option D is the correct answer.

None is right!
We should have a deny statement instead!
#ip prefix-list seq 10 deny 10.0.0.0/8 ge 9 (denies 10 prefixes)
#ip prefix-list seq 10 permit 0.0.0.0/0 le 32 (allows eveything else)

Correct answer: D
ip prefix-list EIGRP seq 10 permit 10.0.0.0/8 le 32
@ellen_AA:
I think the goal is to allow the prefixes inside 10.0.0.0/8, not deny them.
So we need to add 'le 32' statement in the permit sequence.

I am confused, doesn't the question say the engineer is filtering most of the 10 networks rather than allowing them? I am very confused by this question.

No, the prefix-list is filtering the prefixes instead of allowing them. Therefor he needs to allow them. Answer D
