In a directed graph, if there is a path from each vertex to every other vertex, then it is called :

  • A.Weakly connected
  • B.Tightly connected
  • C.Strongly connected
  • D.Loosely connected

Answer: C

Such a directed graph is strongly connected.

A directed graph is strongly connected when there is a directed path from every vertex to every other vertex, following the edge directions.

It is weakly connected if it becomes connected only when edge directions are ignored. 'Tightly connected' and 'loosely connected' are not standard terms for this property.
