About 96% of Scandinavian moths have ears tuned to the ultrasonic pulses that bats, their predators, emit. But the remaining 4% do not have ears and are deaf. However, they have a larger wingspan than the hearing moths, and also have higher wing-loadings the ratio between a wing’s area and its weight — meaning higher maneuverability.

The deaf moths have all the abilities for better maneuverability - for frequent changes in flight direction. So, deaf moths may try to avoid their predators by frequently changing their flight patterns. Option b) is the correct inference.
