Correct Option: B

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Tasks must be within Workflows in order to be executed - This statement is true. In most workflow systems, tasks are organized within workflows, and the execution flow of tasks is defined by the workflow.

Option B) Workflows must be within Tasks to be executed - This statement is false. Workflows are higher-level structures that define the order and dependencies of tasks. Workflows contain tasks, not the other way around. Tasks are executed within workflows.

Option C) Workflow links may contain conditions - This statement is true. Workflow links can have conditions associated with them, which determine the flow of execution based on certain criteria. These conditions can be used to create conditional branches and control the flow of the workflow.

Option D) A start task is the default task in a Workflow - This statement is false. While a start task is often used to initiate a workflow, it is not a default task in a workflow. A workflow can have multiple entry points or trigger points, depending on the specific requirements of the system.

The correct answer is B) Workflows must be within Tasks to be executed. This statement is false because workflows contain tasks, and tasks are executed within workflows.
