      D Is protected by a semaphore with an initial value greater than 1. Correct Answer Incorrect Answer
      E Is always executed in kernel mode. Correct Answer Incorrect Answer

      A critical section is a segment of code where shared resources are accessed. To maintain data consistency and prevent race conditions, only one thread should be allowed to execute its critical section at any given time.
