( ( O Four vertices (a, b, d, and e) have odd degree. Therefore, the graph does not have an Euler circuit. O Two vertices (b and f) have odd degree. Therefore, the graph does not have an Euler circuit. )All vertices have even degree. Therefore, the graph does have an Euler circuit. )All vertices have odd degree. Therefore, the graph does not have an Euler circuit.
