All edges Ti -> Tj that satisfy one of the following conditions are contained in the set of edges

14. All edges Ti -> Tj that satisfy one of the following conditions are contained in the set of edges:

1. In the case of Ti executing write (Q) before Tj executing read (Q), create node Ti * Tj.
2. If Ti executes the read operation (Q) before Tj executes the write operation (Q), create a node Ti * Tj.
3. When Ti executes write (Q) before Tj executes write (Q), a node Ti * Tj is created.
4. All of the above

Answer: D) All of the above

Explanation:

All edges Ti -> Tj that satisfy one of the following conditions are contained in the set of edges:

2. If Ti executes the read operation (Q) before Tj executes the write operation (Q), create a node Ti * Tj.
3. When Ti executes write (Q) before Tj executes write (Q), a node Ti * Tj is created.
