(iii) Insulates the body
(iv) Makes it a good swimmer
(v) Reduces heat loss
(vi) Makes it walk on snow easily
(vii) Sensitive hearing
A P → (v), Q → (vii), R → (ii)
B P → (iv), Q → (iii), R → (i)
C P → (iii), Q → (v), R → (vi)
D P → (iii), Q → (i), R → (ii)
I have a question, how can small ears help in reducing heat loss?
