Explanation: it illustrates the universal design principle of equitable use, which means that the design is useful and marketable to people with diverse abilities1. A concrete sidewalk ramp is an example of a design that can benefit people with different mobility needs, such as wheelchair users, stroller users, or people with walkers. It provides the same means of access for all users, without segregating or stigmatizing anyone1.
Answer A is not correct, because it does not demonstrate a universal design principle, but rather an individual adaptation or accommodation. A head pointer is a specialized device that is not widely available or usable by most people. It does not meet the criteria of equitable use, flexibility in use, simple and intuitive use, perceptible information, tolerance for error, low physical effort, or size and space for approach and use1, which are the seven principles of universal design.
Answer B is not correct, because it does not show any specific design feature that is relevant to the universal design principles. Pushing carts in the parking lot is a job task that may or may not be accessible or usable by people with diverse abilities, depending on the design of the carts, the parking lot, and the store. It is not clear how this example relates to any of the universal design principles.
Answer D is not correct, because it is also an example of an individual adaptation or accommodation, not a universal design principle. A picture prompt list is a personalized tool that may help some people with cognitive disabilities, but it is not a design that is applicable or beneficial to all users. It does not meet the criteria of the universal design principles. References
