How many oxygen masks will drop in the lavatory?

In most modern aircraft, the design is such that there are a specific number of oxygen masks provided for passenger safety in areas like the lavatories. Based on standard configurations and safety regulations, the correct answer reflects that typically two oxygen masks will deploy in the lavatory area.

This is based on the rationale that the lavatory is often utilized by more than one passenger at a time, and providing two masks ensures that both individuals can have access to supplemental oxygen in the event of cabin depressurization, enhancing safety during emergencies. Each mask can be deployed independently, catering to the needs of two persons simultaneously.

Understanding the specific number of oxygen masks in various aircraft configurations is crucial for ensuring that all passengers have adequate safety measures in place during emergency situations.
