B Correct answer
Explanation

Hippos produce a red-colored secretion often called 'blood sweat,' though it's neither blood nor sweat. This secretion contains pigments that act as sunscreen and antibiotic. The red color comes from hippopotamic acid and norhippopudic acid. 'Taurus' refers to zodiac signs or cattle, not a specific animal.
