The correct answer is (D) Bat.

Bats are well-known for using echolocation, a biological sonar system, to navigate and locate prey in darkness or low-light conditions. They emit high-frequency sound pulses and interpret the returning echoes.

Rattlesnakes use pit organs to detect infrared radiation (heat) from prey. Barn owls have exceptional hearing and vision adapted for nocturnal hunting. Grasshoppers primarily rely on vision and auditory senses (though not echolocation).
