When a thread executing a synchronized statement completes or satisfies the condition on which another thread may be waiting, it can call Object method notify() or notifyAll() to allow a waiting thread or all waiting threads to transition to the runnable state again. The notify() method wakes up only one thread that is waiting on the object while the notifyAll() method wakes up all threads waiting on the object. Therefore, the best choice for this question is either C (notify, notifyAll).
