Solution

The correct option is D Hamiltonian path

A path in graph G, Hamiltonian path contains every vertex of G once and only once.

A Hamiltonian circuit in a graph G is a circuit that includes every vertex (except first/last vertex) of G exactly once. An Eulerian path in a graph G is a walk from one vertex to another, that passes through all vertices of G and traverses exactly once every edge of G.

A Hamiltonian path is an undirected or directed graph that visits each vertex exactly once. A Hamiltonian cycle (or Hamiltonian circuit) is a Hamiltonian path that is a cycle.
