The primary purpose of the 'Controlling a Stage' process in PRINCE2 is to monitor and control progress against the plan. This process is essential in ensuring that the project stays on track and meets its objectives as outlined in the project plan. Throughout a project, it is crucial for project managers to regularly assess the performance of the project against established parameters such as time, cost, quality, and risk.

By focusing on monitoring and controlling, project managers can identify any deviations from the plan early on, allowing them to take corrective actions if necessary. This proactive approach helps maintain control over the project, ensuring that it progresses smoothly through each stage.

In terms of other options, while engaging stakeholders and finalizing deliverables are important aspects of project management, they are not the central focus of the 'Controlling a Stage' process. This process does involve stakeholder communication and finalization of work products, but these activities support the primary aim of monitoring and controlling project progress. Similarly, initiating new project phases is part of the overarching project lifecycle but falls more under the 'Managing Stage Boundaries' process rather than the specific focus of 'Controlling a Stage'.
