Which ABPs go out next after the window ABPs?

• A. B and E
• B. A and F
• C. C and D
• D. G and H

Answer: (A)

The main idea here is readiness and sequencing: after the window ABPs are out, you look for which ABPs have all their prerequisites satisfied and don’t depend on any other ABPs that are still pending. Those ABPs are the ones that can go next.

In this case, the ABPs that are immediately eligible are B and E. They don’t require any other ABPs to have left first and they don’t collide with the constraints governing the next steps, so they can depart right after the window ABPs. The other options would need either ABPs that haven’t been released yet or would violate the established order, so they aren’t the correct next pair.
