Which of the following is a graphical representation of roles and responsibilities of different project team members?

A RACI chart is a graphical matrix used in project management to define and display the roles and responsibilities of each team member in relation to project tasks or deliverables. The four designations - Responsible, Accountable, Consulted, and Informed - ensure clarity around who does the work, who owns it, who provides input, and who is kept updated.

A Pareto chart is a quality management tool that displays defects or issues in descending order of frequency to identify the most significant causes, not a representation of team roles and responsibilities.

A resource histogram chart shows the quantity of resources allocated over time, focusing on workload distribution rather than defining specific roles and responsibilities for each team member.

An organization chart shows the hierarchical reporting structure of an organization, not the specific task-level roles and responsibilities assigned to team members on a project.
