• A. 2
• B. 4
• C. 6
• D. 8

Answer: (B)

The A220-100 is designed with four emergency exit doors to enhance passenger safety and facilitate quick evacuations in emergency situations. These exits are strategically placed to ensure accessibility, allowing for an effective egress path in the event of an emergency. The configuration of four exits aligns with the aircraft's size and passenger capacity, providing a balance between safety regulations and practical design.

Having four doors helps ensure that evacuation procedures can be performed quickly and efficiently, accommodating the number of passengers typically found on this narrowbody aircraft. This design consideration is crucial in maintaining compliance with aviation safety standards, which dictate the number of exits based on aircraft seating capacity and layout.

The other numbers presented in the choices do not align with the specifications of the A220-100. Thus, the selection of four exits is essential for understanding the aircraft's safety features and operational guidelines.
