A traversable graph is one you can draw without taking your pen off the paper, and without going over any edge twice.
We have to check the option that is the path given can be drawn without pen off and also without going over any edge twice.
1. The first path , A, B, C, D, E, A, B, D, E, B is clearly going over the edge DE twice.
Therefore , the path does not traversable the graph.
2. The second path C, B, A, D, E, C, D, A, E, B, D
