Correct answer: B

To find the minimum spanning distance, we use Kruskal's Algorithm. Since there are 5 vertices (A, B, C, D, E), the Minimum Spanning Tree must have exactly 4 edges.

1. List all edges sorted by weight: AB(1), DE(2), BE(3), BD(4), BC(5), CE(6), AC(7).

2. Select edges without forming cycles:

  • Select AB (1).

  • Select DE (2).

  • Select BE (3). This connects the components {A,B} and {D,E}.

  • Skip BD (4) as it creates a cycle with BE and DE.

  • Select BC (5) to connect vertex C.

Total Weight: 1 + 2 + 3 + 5 = 11. Number of Edges: 4.
