What does "mobility" refer to?

The term "mobility" refers to the capability of moving or being moved freely and easily. It often encompasses both physical movement, such as the ability to walk or travel, as well as the capacity to change positions or adapt to different circumstances. In a broader context, mobility can also refer to social or economic movement, indicating how individuals or groups can navigate through various situations or environments.

In choosing the correct response, it is important to recognize that options like stability, ability to be still, and inflexibility contrast sharply with the fundamental meaning of mobility. Stability implies a lack of movement or change, while the ability to be still directly negates the concept of movement. Inflexibility further emphasizes rigidity and an unwillingness or inability to change positions or adapt. Thus, option C, which describes movement, is the only choice that aligns with the meaning of mobility.
