Answer:
C. Mental ability/disability
Explanation:
Among the options provided, mental ability/disability would represent an internal dimension of diversity. Internal dimensions of diversity are aspects that individuals typically have little control over and that are not immediately visible or observable. Mental ability/disability refers to variations in cognitive functioning and mentalprocessing, which can vary among individuals and impact their experiences and perspectives. Unlike family status, work experience, and education, which are external dimensions of diversity that can be influenced or acquired over time, mental ability/disability is an inherent aspect of an individual's identity and can significantly shape their thoughts, emotions, and behaviors.
