Which three requirements must a correct solution to the critical-section problem satisfy?
Correct answer A. Mutual exclusion, progress and bounded waiting
Explanation
Mutual exclusion means only one process is in its critical section at a time; progress means that if none is inside, the choice of who enters next cannot be postponed forever; bounded waiting limits how many times others can enter ahead of a waiting process. Hold and wait, no preemption and circular wait are deadlock conditions, and atomicity, consistency and durability are database transaction properties.
