To answer this question, we need to analyze what components are present in a precedence graph related to transactions in a schedule.

1. **Understanding Precedence Graphs**: A precedence graph is a directed graph used to represent the relationships between transactions in a database system, where the nodes (or vertices) represent the transactions, and the directed edges represent dependencies between them.

2. **Identifying Components**: In the context of the question, we need to determine which term logically fills in the blank based on standard terminology used in transaction management:
- **a. None of these**: This option suggests that the answer may not be listed among the other choices.
- **b. Vertices**: This refers to the nodes of the graph, which indeed represent the different transactions.
- **c. Directions**: This typically relates to the orientation of edges but is not a set in the graph.
- **d. Edges**: These represent the relationships or dependencies between transactions.

3. **Conclusion**: The correct term to fill in the blank is “Vertices,” as it corresponds to the set consisting of all transactions participating in the schedule within the precedence graph.

### Final Answer
The set of **vertices** in a precedence graph consists of all the transactions participating in the schedule.
