What does mobility refer to?

Mobility refers to the ability to move, whether it’s in a physical sense, such as the capability to walk or travel from one place to another, or in a social context, like the ability to change one’s social status or class. The key aspect of mobility is movement, indicating freedom and capability to relocate or shift position, which is fundamental to various aspects of life, including transportation, employment opportunities, and social dynamics.

In contrast, the other options emphasize different concepts. Staying still pertains to immobility, changing opinions relates to adaptability in thoughts rather than physical movement, and accumulating wealth does not directly address the concept of movement but rather focuses on economic status. Thus, the emphasis on movement makes the answer about the ability to move the most accurate.
