Three vertices have the highest degree: F, H and K.

The graph is not connected.

Step-by-step explanation:

The degree of a vertex is the number of edges incident on that vertex. In this graph, there are three vertices having the highest degree (4) : F, H and K.

The graph is not connected as there aren't any paths joining vertex N with any of the other vertices.
