What is the primary function of Workflow Automation within Cloud Pak for Business Automation?

The correct answer is C. Workflow Automation in Cloud Pak for Business Automation is the capability that orchestrates multiple business processes, including straight-through processes, human-assisted processes, and case-management work, while providing visibility into each step. This definition captures both execution and control: workflow automation sequences work, assigns or delegates tasks, coordinates services, integrates systems, manages case or process state, and enables stakeholders to see where work is in the lifecycle. Option A is incorrect because CP4BA workflow authoring is model-driven and low-code, not focused on low-level programming. Option B is too narrow because Business Automation Workflow explicitly supports case management as well as structured process work. Option D is unrelated; storage management is an infrastructure concern, not the primary function of Workflow Automation. In architecture terms, Workflow Automation is the orchestration backbone that links people, systems, data, rules, and content into executable business operations with runtime visibility and governance.
