Assume you have a digraph with 5 vertices (A, B, C, D, and E) and 9 arcs. B is incident from D, E, and A; C is incident to E and A and incident from D; E is incident to D and incident from A.

Suppose that the vertices of the digraph represent individuals and there is an arc going from vertex X to vertex Y if and only if X "likes" Y. Which of the following statements [A), B), C), or D)] is not true?
◦ C likes A but A does not like C.
◦ B does not like A, C, D, or E.
◦ A likes B and E but does not like C or D.
◦ B and C do not like each other.
◦ all of these statements are true.

Vertex A has
◦ indegree 1, outdegree 2.
◦ indegree 2, outdegree 1.
◦ indegree 0, outdegree 3.
◦ indegree 3, outdegree 0.
◦ none of these
