B)short.
C)ultrasonic.

Question

Quizplus · Accepted Answer

Long wavelengths of sound carry farther in air because they can diffract around obstacles and are less affected by air resistance. Short wavelengths are absorbed and scattered more easily in the air, causing them to lose energy and travel shorter distances. Ultrasonic waves have frequencies higher than the range of human hearing and are not well transmitted through air, therefore they are not a good choice for carrying sound farther.
