There are three routers on a Gigabit Ethernet LAN: Router A, Router B, and Router C. Router A is the Designated Intermediate System (DIS) at Level 1 for that LAN. Router A‘s DIS priority is 64. The LAN is a Level 1-only link. Router D has just been powered up on that same LAN and its DIS priority is 80.Which statement is true?（）A. Router A remains the DIS and generates a new pseudonode LSP for that LANB. Router A remains the DIS and NO new pseudonode LSP is generated for that LANC. Router D becomes the new DIS, generates a new pseudonode LSP for that LAN, and purges the old pseudonode LSP generated by Router AD. Router D becomes the new DIS, does NOT generate a new pseudonode LSP for that LAN, and does NOT purge the old pseudonode LSP generated by Router A
