What exception must be handled when calling the sleep() method on a thread?

InterruptedException
IOException
TimeOutException
ExecutionException

The correct answer is: InterruptedException

The "InterruptedException" exception must be handled when calling the sleep() method on a thread. This exception is thrown when another thread interrupts the sleeping thread, causing it to be woken up and unable to complete its sleep. The other options are incorrect because - IOException is a checked exception related to input/output operations and is not related to thread sleep. - TimeOutException may seem like a valid option, but in reality it is not a standard exception in Java. It is a custom exception that may be defined by the developer. - ExecutionException is also not a valid option because it is a checked exception related to errors and exceptions that occur while running a task on a different thread using the "Executor" interface. It is not directly related to thread sleep.
