### Break Down the Problem
1. Understand the definition of a tree: A tree is a connected graph with no cycles.
2. Identify the relationship between vertices and edges in a tree.

### Relevant Concepts
1. A fundamental property of trees is that the number of edges $ E $ in a tree with $ V $ vertices is given by the formula:
$$
E = V - 1
$$

### Analysis and Detail
1. Given that the number of vertices $ V = 25 $:
$$
E = 25 - 1 = 24
$$

### Verify and Summarize
- The calculations confirm that for a tree with 25 vertices, the number of edges should indeed be 24.

### Final Answer
The required number of edges for the graph to be a tree is **24** (Option a).
