Describe the emergency exit configuration in the ERJ-145.

The emergency exit configuration in the ERJ-145 is designed to ensure passenger safety and efficient evacuation in case of an emergency. The inclusion of several emergency exits, such as over-wing exits and rear doors, allows for a facilitated escape for passengers. This design strategy is crucial for managing evacuations quickly and safely, enabling passengers to exit the aircraft from multiple points rather than having only a single exit.

By having over-wing exits, the ERJ-145 leverages the wings' structure to provide additional escape routes that are easily accessible and help speed up the egress process. The rear exit further enhances the redundancy of escape options available, ensuring that regardless of the situation or blockage at one exit, passengers have alternative avenues to exit. This multi-faceted approach enhances overall safety, making option B the correct choice regarding the emergency exit configuration of the ERJ-145.
