Which of the following is included in a pre-flight safety briefing?

The focus of a pre-flight safety briefing is to ensure all passengers are informed about safety procedures and emergency protocols. This includes explaining the location and operation of emergency equipment, such as oxygen masks and life vests, as well as the exits available on the aircraft. By providing this critical information, flight attendants prepare passengers to respond effectively in the event of an emergency, enhancing their safety during the flight. The other options, while relevant to the overall flight experience, do not pertain to safety protocols and therefore are not included in the safety briefing.
