## Answers

Explanation:

I. Minimum Spanning Tree of G is always unique - MST will wlways be distinct if the edges are unique so Correct II. Shortest path between any two vertices of G is always unique - Shortest path between any two vertices can be same so incorrect Therefore, option A is correct .
