• A. Oxygen masks only
• B. Oxygen for crew and passengers, emergency slides at doors, fire extinguishers, life vests
• C. Life vests only
• D. Emergency signaling devices only

Answer: (B)

Understanding what items are included as standard emergency equipment on the A321. The standard gear covers essentials for breathing, evacuation, fire control, and water survival. Oxygen for crew and passengers ensures everyone can breathe normally in a degraded cabin or smoky conditions. Emergency slides at doors provide a rapid way to evacuate the cabin in an orderly and swift manner. Fire extinguishers are carried to tackle onboard fires and buy time for passengers to evacuate. Life vests are available for passengers in case of a water landing. The other options mention only a single item, which omits other critical components of the standard emergency equipment set.
