Which of the following graphs has an Eulerian circuit?
| A. | Any k-regular graph where k is an even number |
| B. | A complete graph on 90 vertices |
| C. | The complement of a cycle on 25 vertices |
| D. | None of the above |
Answer : D Explanation : In a k-regular graph, all the vertices are of degree k. If all the vertices in a graph have even degree, there exists an Eulerian circuit (or cycle). |
