Which aircraft model is described as Embraer Regional Jet with 76 passengers, including 12 first class seats and 64 Main Cabin/Economy seats (two-class configuration)?

• A. ERJ 175 two class
• B. CRJ 900 (76 PAX) 3 class
• C. A321
• D. B737-800

Answer: (A)

The key idea is matching the cabin layout to the aircraft type. A regional jet from Embraer that seats 76 people in a two-class arrangement—12 in first class and 64 in main cabin/economy—fits the ERJ 175 model. This configuration is a classic two-class setup for that aircraft family.

The other options don’t align with that description. The A321 and B737-800 are larger jets with far more seats, not typical regional jets. The CRJ900 is a Bombardier regional jet and, in this context, isn’t the Embraer model described, and its typical seating arrangements differ from the specified two-class 12/64 layout.
