Option B

Pigs wallow in the mud to cool themselves down.

Explanation: Pigs' skin contains lots of fats, and fats serves as thermal insulator during cold (low temperatures); unfortunately, this feature turns becomes a disadvantage during heat (high temperatures). Hence, pigs frequently wallows in the mud (or any nearby cool water place) - to reduce their body temperature.

b. To cool themselves down

Explanation:

the number of sweat glands is very less in pigs as compared to our body and some of the sweat glands do not work as well. wallowing in mud, help the pigs to regulate the body temperature and keeps their body cool when its too hot outside. The water in mud evaporates slowly  than the pure water .
