The explanation is accurate.
The command issued, says show me routes that are learned via EIGRP.
as stated the 10.25.67.33 is an ip address which is part of the subnet
10.25.67.32, that is why A is wrong and C is right
b is an IP address, not a subnet so it is wrong.
D is the subnet between the routers, but it is a connected route (on router b), not a route learned from EIGRP
E is also a connected route (on router b), not a route learned via EIGRP.

Yeah, it would show routes learned via EIGRP, which would be by the subnet, not the individual IP address. The easiest way to remember that is that the routes refer to the direction of that entire network, not just the one IP address.

This is an excellent explanation by M4verick. When you look at the routes in the routing table (show ip route) it is going to show you just as M4verick said, the route to that particular network or subnet.
Think of it this way, this goes back to the fact that when a packet comes in, it is compared to the routing table. That packet is then forwarded out to the next hop, with the longest match. Say that a packet comes in with the destination IP: 10.25.67.33 /27
Destination IP: 10.25.67.33 /27
10.25.67.32 /27 or
As you can see 31 bits match... Hope this doesn't confuse you just trying to help explain what it really boils down to.

I understand routing. Once I realized its really just a subnetting question, I answered it in about 10 seconds. I thought that there was some underlying eigrp concept that I was missing. I feel dumb for not thinking to subnet it first.
