Suppose G is a simple, nonconnected graph with n vertices that is maximal with respect to these properties. That is, if you tried to make a larger graph in which G is a subgraph, this larger graph will lose at least one of the properties (a) simple, (b) nonconnected, or (c) has n vertices. What does being maximal with respect to these properties imply about G?G? That is, what further properties must GG possess because of this assumption? In this...
