Which of the following is not a subgraph of this graph?
{(1,3), (3,2), (5,8), (3,6), (9,7)} {(0,4), (3,2), (5,8), (3,6), (9,7)} {(1,7), (3,2), (5,8), (5,6), (9,7)} {(1,7), (3,2), (5,8), (3,6), (9,7)}
No, because the sum of the friends given is odd
No, because the number of edges in this graph is odd No, because the sum of the edges is not divisible by 9
