Which of the following equipment is commonly used for individuals with disabled hands?

The choice of small rubber roller as the correct answer highlights its utility for individuals with disabled hands. This tool is designed to provide a better grip and facilitate movement, making it easier for those with limited dexterity to perform tasks that require the rolling action for applying ink or other materials. The design of a small rubber roller typically allows for more control and less strain on the hands, which is particularly beneficial for those who may struggle with traditional tools.

On the other hand, while a spatula and an inking plate may serve practical purposes in various settings, they do not offer the same ergonomic advantages for individuals with hand disabilities. A spatula often requires a more complex motion that may be difficult for those with limited hand mobility, and an inking plate is typically used as a surface for mixing inks rather than as a handling tool. The cardholder, while potentially helpful for holding items, does not offer the same level of assistance in motion and force distribution as the small rubber roller does.
