What defines a Continuation Task in Task programming?

1. A Task that is run immediately after another Task has finished

2. A Task that interrupts another Task's execution

3. A Task that runs only on failure of another Task

4. A Task that is created by multiple Tasks

The correct answer is: A Task that is run immediately after another Task has finished

A Continuation Task is fundamentally defined by its execution sequence in relation to another Task. Specifically, it is designed to run immediately after the completion of a preceding Task. This means that the continuation is contingent upon the successful finish of the initial Task, and it allows for a more organized flow of operations where subsequent actions depend on the results of prior tasks. For instance, if the first Task processes data and the second Task needs to handle that data after the first Task completes, the second Task would be identified as a Continuation Task. This allows for chaining of tasks and is essential for creating more complex workflows in asynchronous programming. In contrast, other definitions of Tasks mentioned do not align with the characteristic of Continuation Tasks. A Task that interrupts the execution of another does not represent a continuation, rather it suggests preemption or interruption. Similarly, a Task that runs only on the failure of another Task indicates error handling rather than continuation of the process. Lastly, the notion of a Task being created by multiple Tasks diverges from the idea of a continuation since it implies simultaneous initiation rather than sequential execution.
