In this network presented in the following exhibit, traffic destined for 10.1.3.1 arrives at P4S-R5. Which path will be taken by the traffic from here and why?
A) It will take the path P4S-R3, P4S-R2, P4S-R1, because OSPF always prefers paths within an area.
B) It will not take any path; the traffic will be dropped because P4S-R2 is in a different autonomous system than P4S-R1 or P4S-R3.
C) It will take the path the path P4S-R4, P4S-R3, P4S-R2, P4S-R1, because this is the lowest cost path.
D) It will not take any path; the traffic will be dropped because the summary (type 3) LSA advertised by P4S-R1 into area 1 will not be readvertised back into area 0.
