The correct answer is the anteroom, which serves as a controlled environment for personnel prior to entering the buffer room. The purpose of the anteroom is to reduce the risk of contamination to the sterile compounding environment found in the buffer room.

Within the anteroom, personnel can don appropriate personal protective equipment (PPE), such as gowns, gloves, masks, and hair covers, ensuring they meet the necessary cleanliness standards before they proceed. The anteroom may also have specific controls related to airflow, cleanliness, and humidity, further ensuring that any personnel transitioning to the buffer room do not inadvertently introduce contaminants.

A containment area is typically used for hazardous materials, while a cleanroom corridor might refer to a general passageway that connects cleanrooms but does not specifically pertain to the controlled preparation environment. The compounding area refers to the main workspace where sterile preparations are made but does not serve the preparatory role that the anteroom fulfills.
