The side reach from a wheelchair should be between ____" and ____".

The range for side reach from a wheelchair is critical for ensuring accessibility and functionality for individuals with mobility challenges. The correct choice indicates that the side reach should be between 9 inches and 54 inches. This range allows individuals who use wheelchairs to comfortably and effectively access items within this space without straining or compromising their position.

In a practical application, this means that objects such as shelves, tables, or controls need to be placed within this distance to facilitate easy access. It's essential for both safety and independence, as reaching beyond this range can pose difficulties for users due to limited mobility and the need for stability.

The other ranges provided do not align with established accessibility guidelines, which is why they are not suitable answers in this context. This specified range of 9 inches to 54 inches is consistent with standards for barrier-free architecture and universal design principles, which aim to create environments accessible to all users.
