What characterizes a C cane?

A C cane is characterized by its straight design and a curved handle at the top, which is designed to provide a secure grip and improve the user's comfort and stability while walking. The curved handle allows for better body mechanics, as it enables the user to put weight on the cane more comfortably, often making it easier for individuals with balance issues or mobility challenges to use.

The other options describe canes with different configurations or purposes. For example, a cane with four rubber-tipped feet is known as a quad cane, which offers additional stability but does not resemble a C cane. Similarly, a cane specifically designed for use with wheelchairs would not fulfill the characteristics of a C cane, as its design and use are entirely different, focusing instead on supporting individuals in a seated position. Lastly, a cane with a wider base, which might be designed to provide extra stability, also does not fit the description of a C cane, which is primarily defined by its straight shaft and curved handle.
