What is the purpose of a pre-flight safety briefing?

The purpose of a pre-flight safety briefing is fundamentally about passenger safety. It informs passengers about important safety procedures and equipment that they need to know in order to respond effectively in case of an emergency. This includes information on the use of seat belts, how to locate emergency exits, and how to properly use oxygen masks, among other critical safety protocols. By providing this information during the briefing, flight attendants ensure that passengers are aware of how to keep themselves safe during the flight and know what actions to take in the event of an emergency.

Option A does not capture the essential purpose, as the briefing is not meant to simply pass time, but to convey crucial information. While introducing the flight crew could be part of the briefing, it is secondary to the main goal of ensuring passenger safety, making option C less relevant as a primary objective. Additionally, explaining the in-flight menu is unrelated to safety and thus does not align with the core reason for conducting a safety briefing, which is illustrated in option D.
