Which of the following graphs have Euler circuits or Euler trails? E D R A: Has Euler trail. A: Has Euler circuit. G V C B I H C: Has Euler trail. C: Has Euler circuit. U V U B: Has Euler trail. B: Has Euler circuit. H V D: Has Euler trail. D: Has Euler circuit.

B A. Determine whether the graph contains an Euler path or an Euler circuit. Select the one best response. The graph contains at least one Euler path, but no Euler circuit. O The graph contains at least one Euler circuit (which is also an Euler path). The graph does not contain any Euler paths nor Euler circuits.

Analyze each graph below to determine whether it has an Euler circuit and/or an Euler trail. •If it has an Euler circuit, specify the nodes for one.•If it does not have an Euler circuit, justify why it does not.•If it has an Euler trail, specify the nodes for one.•If it does not have an Euler trail, justify why it does not.
