An enterprise is adopting a new governance framework. Of the following, the MOST effective method to help ensure that key activities are performed by appropriate resources is through the use of:

A RACI (Responsible, Accountable, Consulted, Informed) chart clearly defines roles and responsibilities for specific tasks or decisions within a project or process. By assigning each key activity to the appropriate stakeholders with R, A, C, or I roles, it directly ensures that the right resources are involved and performing the necessary actions.

An organizational breakdown structure (OBS) defines the project's organizational hierarchy but does not detail who is responsible for specific tasks.

A work breakdown structure (WBS) decomposes a project into smaller, manageable tasks, but it does not assign specific roles and responsibilities to those tasks.
