A category B aircraft has a speed ___ knots or more but less than ___ knots.

This item tests how aircraft are grouped by speed into distinct bands for traffic management. Category B is defined as speeds of 91 knots or more, but less than 121 knots. That means any aircraft flying at 91 up to 120 knots falls into this category, while speeds below 91 belong to the slower category and speeds at 121 knots or more belong to a faster category. Using a lower bound of 91 and an upper bound just under 121 creates a clear, non-overlapping range so procedures and spacing can be applied consistently. The other options either miss a bound or place the band in a different speed interval, so they don’t match the defined Category B range.
