Which anatomical adaptation helps an elephant regulate its body temperature?

Question

A Large ears increase surface area so that more heat is lost by radiation
B A large stomach stores a lot of water to make up for moisture loss due to seating
C A large trunk smells water from far away and guides the elephant to it

Answer 1

A. Large ears increase surface area so that more heat is lost by radiation.

Elephants have large ears that serve to dissipate heat, allowing them to regulate their body temperature more effectively in hot environments. The increased surface area of their ears facilitates heat loss through radiation.
