Answer

Answer:

D. infrasound

Brief Explanation:

Infrasound refers to sound waves with frequencies below the human - audible range (below 20 Hz). Infrared is related to electromagnetic waves, not sound. Seismology is the study of earthquakes. Geosound is not the correct term for low - frequency sound waves humans can't hear.
