Explanation
EIGRP (Enhanced Interior Gateway Routing Protocol) is unique in that it can be configured to operate both as an Interior Gateway Protocol (within an autonomous system) and as an Exterior Gateway Protocol (between autonomous systems), making it the only protocol among the choices with this dual capability. RIP (v1 and v2) and IGRP are strictly IGPs with no support for inter-AS routing. BGP is the standard EGP, but it is not listed among the choices. EIGRP's flexibility across AS boundaries distinguishes it here.
