Which of the following is a set of interrelated actions and activities performed to achieve a prespecified product, result, or service?

A process is officially defined as a set of interrelated actions and activities performed to create a pre-specified product, service, or result. Each process is characterized by its inputs, the tools and techniques that can be applied, and the resulting outputs. Project management itself is accomplished through the application and integration of various project management processes, which are logically grouped into Process Groups (e.g., Initiating, Planning, Executing, Monitoring and Controlling, and Closing). The question provides the exact definition of a process as used by the Project Management Institute (PMI).
