Which document outlines the tools, activities, and responsibilities for managing project requirements?

The correct answer is the requirements management plan. This document is specifically designed to outline how project requirements will be managed throughout the project lifecycle. It details the processes and procedures for gathering, analyzing, validating, and managing requirements, ensuring that all stakeholders understand their roles and responsibilities in this context. The requirements management plan also defines the tools and techniques that will be used for requirement management, the approach to be taken for tracking changes, and methods for communicating about requirements.

In contrast, requirements analysis focuses on understanding and articulating what the requirements are and is a subset of the overall requirements management activities. Requirements documentation is more about capturing and recording the requirements themselves rather than outlining the management process. The project charter is a broader document that defines the project's scope, objectives, and key stakeholders but does not specifically address requirements management in detail. Thus, the requirements management plan is the most comprehensive and relevant document for managing project requirements effectively.
