Let G be any connected, weighted, undirected graph.

I. G has a unique minimum spanning tree, if no two edges of G have the same weight.

II. G has a unique minimum spanning tree, if, for every cut of G, there is a unique minimum-weight edge crossing the cut.

Which of the above two statements is/are TRUE?

Option A. I only

Option B. II only

Option C. Both I and II

Option D. Neither I nor II

True Answer C

##### Explanation :

If no two edges of G have same weight surely G will have unique spanning tree is true.
So I is true
Also if, for every cut of G, there is a unique minimum weight edge crossing the cut then G will have unique spanning tree is also true. So II is true
[Note: The converse of II is not true, but that is not relevant to this question]
So both I and II are true.
Option (d) is correct.

Let G be any connected, weighted, undirected graph.

I. G has a unique minimum spanning tree, if no two edges of G have the same weight.

II. G has a unique minimum spanning tree, if, for every cut of G, there is a unique minimum-weight edge crossing the cut.
