Which of the following statements is/are TRUE for undirected graphs?
P: Number of odd degree vertices is even.
Q: Sum of degrees of all vertices is even.
A and C are odd degree of vertices so number of odd degree vertices = 2 so P is True and sum = 3 + 2 +3 +2 = 10 which is even
so P and Q are both true option C
