Degree of a graph with 12 vertices is _______

A. 25

B. 56

C. 24

D. 212

This question was addressed to me during an online exam.

Question is taken from Graphs in portion Graphs of Discrete Mathematics

Right option is C. 24

To explain: Number of edges incident on a graph is known as degree of a vertex. Sum of degrees of each vertex is called total degree of the graph. Total degree = 2 * number of vertices. So, if there are 24 vertices then total degree is 24.
