Which router translates the Type 7 LSAs into Type 5 LSAs, according to RFC 1587 (OSPF NSSAOption) in an OSPF NSSA with more than one ABR?() A. The router receiving the route translates the Type 7 LSA into a Type 5 LSA.B. The ABR with the lowest router ID translates all Type 7 LSAs into Type 5 LSAs.C. The ABR with the highest router ID translates all Type 7 LSAs into Type 5 LSAs.D. All ABRs translate the Type 7 LSAs into Type 5 LSAs depending on which one has the lowest cost to the route.
