Edge which connect a vertex to a vertex that is neither its ancestor nor its descendant.a)Forward edgesb)Back edgesc)Cross edgesd)None of the mentioned
Solution
The answer is c) Cross edges.
In graph theory, a cross edge is an edge that connects a vertex to another vertex that is neither its ancestor nor its descendant in a depth-first search tree. This means that cross edges can connect vertices that are at the same level in the tree, or they can connect a vertex to a vertex at a different level, as long as the second vertex is not directly above or below the first vertex in the tree.

The result of a depth-first search of a graph can be conveniently described in terms of a spanning tree of the vertices reached during the search. Based on this spanning tree, the edges of the original graph can be divided into three classes: forward edges, which point from a node of the tree to one of its descendants, back edges, which point from a node to one of its ancestors, and cross edges, which do neither. Sometimes tree edges, edges which belong to the spanning tree itself, are classified separately from forward edges. If the original graph is undirected then all of its edges are tree edges or back edges.
