Question
**Question**: For a simple connected graph \( G=(V,E) \) with no multi-edges and no self-loops, what is the range of possible values of \( |E| \)?

- **a.** \( 0 \leq |E| \leq \infty \)
- **b.** The range is not limited
- **c.** \( 0 \leq |E| \leq |V|^2 \)
- **d.** \( |V| - 1 \leq |E| \leq \frac{|V|(|V| - 1)}{2} \)
- **e.** \( |V| \leq |E| \leq |V|^2 \)

**Explanation**: This problem addresses the possible range of edge counts \( |E| \) in a simple, connected graph. In such a graph, conditions like no multi-edges and no self-loops are imposed. Option (d) provides a range starting at \( |V| - 1 \), which is the minimum number of edges for the graph to remain connected (a tree), up to the maximum number of edges \(\frac{|V|(|V| - 1)}{2}\), forming a complete graph \( K_{|V|} \).
