Directed acyclic graphs
Select all statements that are true.
Every directed graph that has a node with no incoming edges is a DAG.
For every DAG G, for any nodes u and v of G, there exists at most one path from u to v in G.
In any DAG G, if (u,v) is an edge of G, then DFS(v) will never discover u.
Every DAG has at least one node with no outgoing edges.
