Which of the following is a key part of a flight attendant's role during boarding?

Assisting with baggage placement is a key part of a flight attendant's role during boarding because it directly contributes to the safety and comfort of all passengers onboard. Properly storing baggage helps maintain aisle space available for boarding and ensures that items are stowed securely to avoid shifting during the flight. Flight attendants are trained to guide passengers on where to place their carry-on bags, ensuring that larger items are stowed in the overhead bins while smaller ones can be kept under the seat. This assistance not only expedites the boarding process but also plays a critical role in maintaining an organized and safe cabin environment.

The other choices relate to responsibilities outside of the immediate processes of boarding. For instance, checking flight logs generally pertains to flight operations and is not a primary customer-facing task during boarding. Making in-flight meal choices comes into play at a different stage during the flight when the service begins. Monitoring restrooms, while important for overall cabin hygiene and availability, does not specifically relate to the boarding phase, where the focus is on getting passengers settled and ready for takeoff.
