Solution

The correct option is B Both B and C
Bats and Whales use an advance echolocation system or SONAR system to communicate and hunt their prey. It involves production of ultrasonic waves which then reflect back from any obstacles on their paths.
Otters use sounds like grunts, whistles, growls, snarls, cooing, etc for communication.
So the correct answer is 'Both B and C'.
