R1 and R2 are two adjacent routers using RIP routing protocol in an autonomous system. The routing table of R1 is shown in figure (a). As shown in figure (b), R1 receives the (V, D) message sent by R2, and the distance of the four routing table items of R1 after the update is 0, 4, 4, and 2 from top to bottom. So the possible data among a, b, c, and d in figure (b) may be ( )
