Need ! the following graph is an efficient network? question 2 options: true. this network uses the least amount of edges to connect all vertices. false. this network has a cycle making it inefficient. true. this network has a cycle making it efficient. false. it doesn't have enough edges to connect all the vertices.

The correct option is 2.

Step-by-step explanation:

In the given figure, there are 5 vertices and 5 edges.

In an efficient network, if we have n vertices, then (n-1) edges are required to connect all vertices.

Let the vertices are A, B, C, D and E.

The edges BC, CD, and DB form a cycle. If we remove any edge from these edges, then we have enough edges to connect all the vertices.

Therefore the statement "Given graph is an efficient network" is false. This network has a cycle making it inefficient and option 2 is correct.
