Dogs and Humans are the only animals with prostates.
A
Correct answer
Explanation
Dogs and humans are indeed among the few mammals with well-defined prostate glands. The prostate is present in most male mammals but varies considerably in size and structure between species. Canine prostates are anatomically and functionally similar to human prostates, which is why dogs are commonly used in prostate cancer research. While other mammals have prostate tissue, humans and dogs have the most prominent discrete prostate glands.
