Which aircraft configuration corresponds to 76 passengers with 12 first class, 12 Delta Comfort+ seats, and 52 Main Cabin seats?

• A. CRJ 900 (76 PAX) 3 class
• B. ERJ 175 two class
• C. A320 180 PAX
• D. B737-700 76 PAX

Answer: (A)

This question tests how a specific passenger mix across cabin classes fits with a particular aircraft’s seating layout. The numbers 12 in First, 12 in Delta Comfort+, and 52 in Main Cabin add up to 76 passengers. That exact breakdown—three distinct cabin offerings with a total of 76 seats—is characteristic of a CRJ-900 configured in a three-class layout.

Other options don’t match that combination: an ERJ-175 in two classes wouldn’t have a separate Delta Comfort+ section, the A320 typically seats far more than 76, and the B737-700 seldom uses a 12/12/52 split. So the CRJ-900 with 76 seats in a three-class arrangement best fits the given counts.
