Answer: B. secrete enzymes that kill bacteria
Explanation:
Paneth cells, so-called because they were first described by Dr. Josef Paneth in 1888, are pyramidal cells, with the nucleus in the basal position, and with large granules in the apical position. Its first isolated specific product was the lysozyme, a bactericidal substance, by Alexander Flemming. These cells play an important role in innate immunity in the small intestine, producing a wide diversity of antimicrobial peptides and enzymes such as lysozyme itself, cryptidines, defensins and a lectin with bactericidal properties.
Fur has a thick layer of protection to help protect..say a bear in this case. A polar bear's fur is helpful in the cold, to prevent the bear from freezing to death.
But since a polar bear eats fish and things that it's used to in Antarctica, it probably won't adapt as easily.
I hope I helped!
