In a RACI matrix, which set of roles is defined?

• A. Responsible, Assigned, Consulted, and Involved
• B. Responsible, Accountable, Coordinated, and Informed
• C. Responsible, Accountable, Consulted, and Informed
• D. Responsible, Administered, Consulted, and Informed

Answer: (C)

RACI defines four role types that clarify responsibility for tasks and deliverables. Responsible refers to the people who actually do the work to complete the task. Accountable is the one who owns the task and must sign off on the result; there should typically be one person accountable per task. Consulted are those whose expertise is sought in two-way communication, and Informed are those kept up-to-date with progress with one-way communication.

This set—Responsible, Accountable, Consulted, and Informed—captures the standard labeling used in a RACI matrix. The other terms in the options (Assigned, Coordinated, Administered, Involved) aren’t part of the conventional RACI framework, so they don’t align with how responsibilities are defined in this model. Understanding these four roles helps prevent ambiguity and ensures everyone knows who does the work, who owns the outcome, who should be consulted for input, and who needs to be informed about progress.
