Final answer:
Both inherent biological conditions and social and environmental factors can cause a disability.
Step-by-step explanation:
The causes of a disability can be both inherent biological conditions and social and environmental factors. A disability can be a result of an individual's biological makeup, such as genetic conditions or physical impairments. Additionally, social and environmental factors, such as unsafe working conditions or limited access to resources, can also contribute to the development of a disability.
For example, certain genetic conditions like Down syndrome or cerebral palsy are considered inherent biological conditions that can cause a disability. On the other hand, environmental factors like exposure to toxins or lack of accessibility in public spaces can also contribute to the development of a disability.
Therefore, the correct answer to the question is C. Both A and B.
