A graph may be defined as a set of points connected by lines called edges. Every edge connects a pair of points. Thus, a triangle is a graph with $3$ edges and three points. The degree of the point is the number of edges connected to it. For example, A triangle is a graph with three points of $2$ degree each. Consider a graph with $12$ points. It is possible to reach any point from any other point through a sequence of edges. The number of edges, $e,$ in the graph must satisfy the condtion

- $11 \leq e \leq 66$
- $10 \leq e \leq 66$
- $11 \leq e \leq 65$
- $0 \leq e \leq 11$
