Explanation

default-information-originate is the standard OSPF command used to advertise a default route (0.0.0.0/0) into an OSPF domain - this is consistent across both Huawei VRP and Cisco IOS, making it the correct answer. Option A (default-route-initiate) and C (ospf default-route) are fabricated commands that do not exist in VRP syntax. Option D (default-route-advertise) sounds plausible but is the correct BGP command on VRP for advertising default routes, not OSPF - a common trap for candidates familiar with multiple protocols.

Memory tip: Think of OSPF needing to originate (create from scratch) a default route into the area - default-information-originate literally says "originate default information." If you see "advertise" in an answer, mentally tag it as BGP.
