Aircraft approach categories are based on stall speed multiplied by 1.3 in the landing configuration. Which option correctly states this factor?

Explanation:
The speeds used to define approach categories come from the stall speed in the landing configuration, with a built-in safety margin. Specifically, the category is based on 1.3 times the stall speed with flaps and gear down. The 1.3 factor provides a buffer above stall to account for gusts, manoeuvring during approach, and pilot inputs, helping ensure the airplane can safely fly the approach and avoid an inadvertent stall. So the correct factor is 1.3 times the stall speed in landing configuration.
