Question : Which of the following statements is true about "Race Condition"?

When multiple processes are accessing shared data without access control and the final result depends on the execution order

When one process is executing in its critical section, no other process is allowed to execute in that critical section.

If the critical section is being used, waiting processes loop continuously at the entry point.

All statements are true.
