单选题You have a Level 1-only router （Router A） in IS-IS area 49.0001. How does Router A learn how to get to IP prefixed in other areas？（）A
Router A must have a Level 2 adjacency with the Level 1/Level 2 router in area 49.0001.B
The Level 1/Level 2 router in area 49.0001 sets the attached bit in the Level 2 LSP it floods into area 49.0001.C
The Level 1/Level 2 router in area 49.0001 sets the attached bit in the Level 1 link-state PDU （LSP） it floods into area 49.0001.D
The Level 1/Level 2 router in area 49.0001 advertises these prefixed into area 49.0001 using a Level 2 LSP it floods into the area.
