Yоu аre perfоrming Dijkstrа’s аlgоrithm on a graph with nodes A, B, C, D, E starting from Node A. The edges are: (A,B,10), (A,C,2), (A,D,1), (C,B,5), (D,E,2), and (E,B,2).Starting from source node A, which sequence of nodes correctly represents the 'Previous Node' for node B as it is updated throughout the execution of Dijkstra’s algorithm?
