Which of the following statements best describes the function of an OSPF Type 4 LSA?
A. A Type 4 LSA is originated by an ABR to describe a route to an ASBR to routers outside the area.
B. A Type 4 LSA is originated by an ABR that is connected to a stub area. The LSA is injected into the stub area to provide routing information.
