What is a digraph?

• a graph with at least 3 vertices

• a graph with at least 3 edges

• a graph that gives direction

• there is no such thing

The digraph shown is a "respect" digraph. Meaning, the vertices of the digraph represent members of a group, and an arc XY represents the fact that X respects Y. Based on this information, who should be the leader of the group?

• A

• B

• C

• D
