You use the Task.Run() method to launch a long-running data processing operation. The data processing operation often fails in times of heavy network congestion. If the data processing operation fails, a second operation must clean up any results of the first operation. You need to ensure that the second operation is invoked only if the data processing operation throws an unhandled exception. What should you do? A. Create a TaskCompletionSource<T> object and call the TrySetException() method of the object. B. Create a task by calling the Task.ContinueWith() method. C. Examine the Task.Status property immediately after the call to the Task.Run() method. D. Create a task inside the existing Task.Run() method by using the AttachedToParent option.
B. Create a task by calling the Task.ContinueWith() method.

You use the Task.Run() method to launch a long-running data processing operation. The data processing operation often fails in times of heavy network congestion. If the data processing operation fails, a second operation must clean up any results of the first operation. You need to ensure that the second operation is invoked only if the data processing operation throws an unhandled exception. What should you do? A. Create a task within the operation, and set the Task.StartOnError property to true. B. Create a TaskFactory object and call the ContinueWhenAll() method of the object. C. Create a task by calling the Task.ContinueWith() method. D. Use the TaskScheduler class to create a task and call the TryExecuteTask() method on the class.
