In an undirected graph, the degree of a vertex is:A. The number of edges incident to the vertexB. The number of vertices adjacent to the vertexC. The sum of the degrees of all verticesD. The product of the degrees of all vertices

The sum of degrees of all vertices in a simple undirected graph is always:a.Equal to the number of vertices in the graphb.Twice the number of vertices in the graphc.Equal to the number of edges in the graphd.Half the number of edges in the graph

What is the degree of a vertex in a graph?a) Number of edges connected to the vertexb) Number of vertices in the graphc) Number of self-loopsd) Number of paths through the vertex

Consider a simple undirected graph with 6 vertices. The degrees of the vertices in this graph are as follows: vertex A has degree 3, vertex B has degree 2, vertex C has degree 4, vertex D has degree 3, vertex E has degree 3, and vertex F has degree 1. Calculate the number of edges in the graph.a.6b.7c.8d.12

In graph theory, what does the degree of a node represent?Select one:a. The direction of edges connected to the node.b. The distance between the node and the farthest node in the graph.c. The number of edges connected to the node.d. The value or weight of the node.

In a digraph, the sum of the in-degrees is equal to:A. The number of verticesB. The number of edgesC. Twice the number of verticesD. Twice the number of edges
