John works as the project manager for Blue Well Inc.

A phase is a combination of associated activities that represent a distinct stage within a project. A phase can have distinct start and finish dates and include several stages of planning and work. Each project has a defined scope of work, such as a unique product or service. Some examples of phases within the scope of work for a project plan are conceptual engineering, pre-construction, and engineering.

Answer option A is incorrect. Concrete is an activity, not a project phase.
