A ______ is a special cycle that passes through every vertex in a graph exactly once.
A)multigraph
B)tree
C)spanning tree
D)circuit

Question

Quizplus · Accepted Answer

A circuit is a closed path in a graph that visits every vertex exactly once. It is also called a Hamiltonian cycle. Therefore, option D is the best choice that matches the given description. A multigraph is a graph that can have multiple edges between the same pair of vertices. A tree is a connected graph without any cycles. A spanning tree is a subset of edges of a connected graph that forms a tree and includes all of the vertices of the graph.
