The given box shows some adaptations shown by different animals. Which of the following options correctly classifies these adaptations in accordance to desert region and polar region?


--------Desert region--Polar region
A(i)----------------(ii), (iii), (iv)
B(i), (iv)----------------(ii), (iii)
C(i), (iii), (iv)----------(ii)
D(ii), (iii)----------------(i), (iv)


This is definitely wrong. Animals of the desert region (mainly camel) produce less urine so that they don’t dehydrate themselves. How is the answer option C.????
