Answer

The path A,B,C,E,G,F,D is a Hamilton path that begins at A and ends at D.

Work Step by Step

A Hamilton path is a sequence of adjacent vertices that visits each vertex in the graph exactly once. Let's start at vertex A. The path can travel to vertex B, and then to vertex C. After this step, the path must travel to vertex E. The path must then travel to vertex G, then to vertex F, and then finally to vertex D. This path is A,B,C,E,G,F,D. Since this path visits every vertex in the graph exactly once, this path is a Hamilton path. This is one Hamilton path that begins at A and ends at D, but there is also another such Hamilton path in the graph.
