### An Undirected Weighted Graph G

**Figure Explanation:**
The figure depicts an undirected weighted graph G with 6 vertices, labeled \( a, b, c, d, e, f \), and 9 edges with specified weights. The arrangement and weights are as follows:

- \( a \) is positioned on the left.
- \( f \) is above and to the right of \( a \).
- \( b \) is below and to the right of \( f \), but above \( e \).
- \( c \) is below and to the right of \( e \), but above \( d \).
- The edges and their weights:
  - \( a \) and \( f \): 1
  - \( f \) and \( e \): 4
  - \( e \) and \( d \): 2
  - \( f \) and \( a \): 3
  - \( e \) and \( c \): 5
  - \( c \) and \( a \): 7
  - \( c \) and \( b \): 5
  - \( a \) and \( b \): 6

**Tasks and Questions:**

**(a) Use Prim’s algorithm to compute the minimum spanning tree for the weighted graph. Start the algorithm at vertex \( a \). Show the order in which the edges are added to the tree.**

**(b) What is the minimum weight spanning tree for the weighted graph in the previous question subject to the condition that edge \((d, e)\) is in the spanning tree?**

**(c) How would you generalize this idea? Suppose you are given a graph \( G \) and a particular edge \((u, v)\) in the graph. How would you alter Prim’s algorithm to find the minimum spanning tree subject to the condition that \((u, v)\) is in the tree?**
