Action Plan Templates in Salesforce Public Sector Solutions are designed to standardize repeatable business processes, such as reviewing a Business License Application. A template can be created for the Business License Application object. This template can include Document Checklist Items, which are specifically used to track the submission and status of required documents like a driver's license. This directly addresses the requirement for the applicant to upload an image. The combination of an Action Plan Template on the correct object with a Document Checklist Item is a standard and intended use of this feature to meet the specified requirements.

B. The reviewer users cannot create their own tasks within a predefined action plan template: This is incorrect. Users with the appropriate permissions can add ad-hoc tasks to an active Action Plan instance, providing the flexibility required by the business process.

C. Action plans cannot have tasks with due dates dependent upon prior tasks within the action plan: This is incorrect. Action Plan task dependencies are a key feature, allowing a task's due date to be calculated based on the completion date of a predecessor task.

D. A document checklist item for an action plan template cannot be created: This is incorrect. Document Checklist Items are a fundamental component that can be added to Action Plan Templates to manage required documentation for processes like applications and permits.

1. Salesforce Help, Public Sector Solutions, "Action Plan Templates": "Create templates for repeatable tasks, and then use the templates to create action plans for individual records, such as business license applications... An action plan template is a reusable framework of tasks and other items." This supports creating a template for the Business License Application object.

2. Salesforce Help, Public Sector Solutions, "Document Checklist Items in Public Sector Solutions": "Use Document Checklist Items to track documents that are required for a business process, such as a license application... Add document checklist items to an action plan template so that they’re automatically included when a user creates an action plan from the template." This confirms that Document Checklist Items can be part of a template, directly supporting option A and refuting option D.

3. Salesforce Help, Public Sector Solutions, "Create Tasks in Action Plans": "Users can add tasks to an action plan after it’s created." This directly refutes option B.

4. Salesforce Help, Public Sector Solutions, "Action Plan Task Dependencies": "Set a task’s start date or due date to be dependent on another task’s completion date. For example, set a task to start 3 days after its preceding task is completed." This directly refutes option C.
