It is impossible to draw a simple graph with five vertices

It is impossible to draw a simple graph with five vertices and edge set { {1, 3}, {2, 3}, {2, 5}, {2, 3}, {3, 5}, {1, 5} } because: It would have an isolated vertex It would have parallel edges O It is possible to draw such a graph It would have a loop
