After an EIGRP router sees a Hello from a neighbor, what parameter(s) does the router not check before establishing a neighbor relationship?

A) Must be on same subnet
B) Must be using the same hello timer and dead timer
C) Must be using the same AS number
D) The source IP address used by the neighbor's Hello must be in the same subnet.

B
Explanation: B) With EIGRP, the Hello timer does not have to match between neighbors for a neighborship to come up, and the dead timer is only used with OSPF.
