Key Role in RACI Model |

D.

In a RACI model, which stands for Responsible, Accountable, Consulted, and Informed, each task or activity is assigned one or more of these roles to clarify who is responsible, accountable, consulted, or informed for that specific task or activity.

• Responsible (R): This role is responsible for performing the task or activity, and they are the ones who actually carry out the work.

• Accountable (A): This role is accountable for the task or activity. They are ultimately responsible for the outcome and have the authority to make decisions and take actions. This role must be assigned to only one individual.

• Consulted (C): This role is consulted for their input and expertise, but they are not responsible for carrying out the task or activity. They provide guidance and advice to the responsible person.

• Informed (I): This role is informed about the task or activity and its progress, but they are not directly involved in the work.

Therefore, the correct answer to the question is D. Accountable, as this role must be assigned to only one individual in order to ensure clear accountability and decision-making authority for the task or activity.
