The following passage should be read carefully and answer the given questions:
Animals communicate with each other in many unique ways. These include signals, facial expressions, body posture, sounds, and special smells released from the body. Song and dance are other means of communication. When animals are trapped in danger, they warn other animals by making sounds like grunting, snorting, or roaring. They also make sounds to call their life partners. Bees inform other members of the hive about the location of food by dancing. Parent birds teach their young ones the techniques of 'flying' by living in the nest. The chicks call their parents for food by making sounds, and their attention is drawn towards food.
Mahasagar is a quiet world full of resonating places. Whales, crabs, shrimp, seals, walruses, seals and dolphins produce various sounds in water such as low humming, chirping, clicking and roaring, whose range extends from infrasound to audible sound for humans. Just as birds are called 'musicians of the sky', similarly seals and dolphins are sometimes called 'musicians of the sea'.

Show answer & explanation
Correct answer: D
The passage mentions sounds ranging from infrasound to audible sound, noting that infrasound is below human hearing limits. The term 'Para-shravya' linguistically implies sounds beyond the range of human hearing, which equates to inaudible frequencies.
