Explanation

VRF-Lite (also called multi-VRF or VRF without MPLS) allows a single router to maintain multiple independent routing tables simultaneously without requiring an MPLS core. It supports several routing protocols including EIGRP, OSPF, BGP, RIPv2, and static routes. EIGRP (option C) is fully supported in VRF-Lite environments, where each VRF instance can run its own separate EIGRP process. IS-IS (option A) is not supported under VRF-Lite because the IS-IS implementation in Cisco IOS does not natively support per-VRF instances in that context. DDR (option B) stands for Dial-on-Demand Routing, which is a legacy WAN connectivity method, not a routing protocol, and is unrelated to VRF. IGRP (option D) is an obsolete Cisco proprietary protocol that has been replaced by EIGRP and is not supported in modern VRF-Lite deployments. Therefore, EIGRP is the correct answer.
