Question: Consider a digraph and a source vertex s with the following properties: edges that leave the source vertex s have arbitrary (possibly negative) edge weights;

Consider a digraph and a source vertex s with the following properties: edges that leave the source vertex s have arbitrary (possibly negative) edge weights; all other edge weigh are nonnegative, and there are no edges from any other vertex to the sources. Does Dijkstra's shortest-path algorithm correctly compute SPT from s in this digraph? Select your answer form the following choices, and briefly explain your answer.

a) Maybe, maybe not (depends on the digraph)

b) Never

c) Always
