B. until another thread issues a notify on the semaphore.
Explanation:
A semaphore is a variable that is shared between threads and is not negative. It also acts as a calling mechanism that uses two atomic operations wait and signal for synchronization of processes.
A thread that is waiting for a process can be signaled by another thread.
A semaphore puts a thread to sleep until another thread issues a notify on the semaphore.
The wait operation will get a semaphore or otherwise wait if the busy S semaphore is available.
The signal operation will release a semaphore or wake a process if there is a thread waiting for S.
