Consider the following matrix: 0 1 0 0 0 01 0 0 A 1 -HOOK 0 0 1 DHC OHOOO OOOH 1 0 0 1 0 0 0 Which of the following is most true? This must be the adjacenty matrix for a digraph (it can't be a regular graph) ()This must be the adjacenty matrix for a graph (it can't be a digraph) This is not a valid adjacenty matrix - that is, there is no graph or digraph that has this for its adjacenty matrix This could be the adjacenty matrix for either a graph or a digraph
