(N/A) $(i)$ $SONAR$ stands for Sound Navigation And Ranging.
$(ii)$ The audible range of sound for human beings is $20 \,Hz$ to $20,000 \,Hz$.
$(iii)$ Bats produce high-pitched ultrasonic squeaks. These sound waves are reflected back to the bat's ears after hitting obstacles or prey. By analyzing these reflections,the bat can locate its prey and navigate in the dark.
