5 votes 5 votes For an spanning forest of a graph with N vertices and C connected components, No of edges should be E=(N-C), but the given graph contains M edges .. So to have spanning forest no of edges to be removed = M- (N-C) = M - N + C Ans - Option C vijaycs answered May 7, 2016 vijaycs comment Share Follow See all 0 reply Please log in or register to add a comment.
