Figure from the original question paper Let G = (V, E) be an undirected graph having distinct positive edge weights. Let V be partitioned into two non-empty sets X and Y. Let e = (s, t) be the minimum cost edge, with s belonging to X and t belonging to Y. Which of the following statement(s) is/are true?\ 1\. The edge e must belong to each path from s to t.\ 2\. The edge e must belong to the minimum cost spanning tree of G. Figure from the original question paper
