D Correct answer
Explanation

Options A, B, and C all cause threads to stop: System.exit() terminates the JVM, higher priority threads can preempt lower priority ones, and the stop() method (deprecated) stops threads. However, option D refers to 'halt method' - the Thread class has no such method. The correct method is interrupt() for cooperative cancellation, or stop() (deprecated), but halt() does not exist.
