Answer:

Introduction:
Different animals have different ways to communicate, and they use it to express their feelings or to warn others of danger. Some animals use sounds to communicate, such as screeching, chirping, or howling. In this question, we need to identify which animal makes a screeching sound.

Explanation:
The correct answer is option 'A,' which is bats. Bats are nocturnal animals that are known for their echolocation abilities, where they use sound waves to navigate and locate their prey. They emit high-pitched sounds through their mouth or nose, and when these sound waves bounce back to them, they can determine the location, size, and shape of the object.

These high-pitched sounds emitted by bats are screeching sounds that are audible to humans. However, the frequency of these sounds is too high, which makes them difficult to hear. Bats can produce sounds up to 110 decibels, which is loud enough to cause discomfort to the human ear.

On the other hand, birds and monkeys produce different sounds that are not screeching. Birds chirp, whistle, or sing, while monkeys make grunting or hooting sounds. Owls, on the other hand, produce a hooting sound that is distinct from the screeching sound of bats.

Conclusion:
In conclusion, bats are the animals that make screeching sounds. They emit high-pitched sounds through their mouth or nose, which they use for echolocation. These sounds are audible to humans, but their frequency is too high, making them difficult to hear.
