Cheapest link algorithm

Suppose the edge 𝑒 is the cheapest edge that crosses the cut (𝐴,𝐵). Then 𝑒 belongs to every minimum spanning tree. To my knowledge, all four options are correct. Options 1, 2 and 4 follow from the Cut property; option 3 is correct because edge weights are distinct. However, including option 1 is turning out to be wrong. Why?

15) The cheapest-link algorithm for solving the Traveling Salesman Problem is: - an approximate and efficient algorithm (because it quickly finds a solution by always choosing the cheapest link, but it may not be the shortest route)Cheapest Link Algorithm Pick an edge with the cheapest weight, in case of a tie, pick Colour your edge.
