Which of the following diseases is a condition that an animal is born with?

Congenital diseases are conditions that an animal is born with, which can result from genetic factors, environmental influences during pregnancy, or a combination of both. These diseases are typically present at or shortly after birth and can affect the animal's development and health throughout its life.

While hereditary abnormalities are also conditions that can be passed down through genetics, this term specifically refers to traits or diseases that are inherited from the parents. On the other hand, degenerative diseases usually develop over time due to factors such as aging or environmental influences, rather than being present at birth. Nutritional diseases arise from dietary deficiencies and are not congenital in nature. Therefore, the most accurate choice that directly addresses conditions an animal is born with is congenital diseases.
