Option 3 : No minimum spanning tree contains emax
Concept:
A minimum spanning tree (MST) or minimum weight spanning tree is a subset of the edges(V – 1 ) of a connected, edge-weighted undirected graph G(V, E) that connects all the vertices together, without any cycles and with the minimum possible total edge weight.
Example:
It cannot always be the case that the edge with emax should not be present in MST.

emax is present in MST.
