To grant authority or power to.

• A. Authorize
• B. Authorized Duty
• C. Empower
• D. Delegate

Answer: (B)

In this context, the important idea is permission tied to a specific task. When authority is given for a particular responsibility, that task becomes an authorized duty—the duty that you are officially allowed to perform because the proper authorization has been granted. This makes authorized duty the best fit for the phrase “to grant authority or power to,” because it pinpoint the result of that permission: a duty that has been approved to be carried out.

Think of it as the practical outcome on the unit: a supervisor grants you permission to perform certain tasks, and those tasks become your authorized duties. The other terms describe the act of granting (authorize), giving general power (empower), or transferring tasks to someone else (delegate), but they don’t capture the notion of a specific task that has been approved to be carried out.
