What happens if a thread calls acquire() on a Semaphore and no permits are available?

  1. The thread terminates

  2. The Semaphore's count is reset

  3. The thread proceeds without waiting

  4. The thread is blocked until a permit is available

The correct answer is: The thread is blocked until a permit is available

When a thread calls acquire() on a Semaphore and there are no permits available, the thread is blocked until a permit becomes available. This means that the thread will pause and wait until a permit is released by another thread.
