What are the principles of universal design?

• A. Equitable use; Flexibility in use; Simple and intuitive; Perceptible information; Tolerance for error; Low physical effort; Size and space for approach and use
• B. Equitable use; Accessibility; Aesthetics; Simplicity
• C. Equitable design; Flexibility; Simple; Perceptible information
• D. Equitable use; Flexibility in Use; Simple and intuitive; Perceptible information

Answer: (A)

Universal design is about creating products and environments that are usable by people with a wide range of abilities and in many contexts. The best answer lists all seven established principles: Equitable use; Flexibility in use; Simple and intuitive use; Perceptible information; Tolerance for error; Low physical effort; Size and space for approach and use.

Equitable use means the design is usable by everyone without segregating or stigmatizing. Flexibility in use allows people to tailor the experience to their preferences or abilities. Simple and intuitive use ensures the design is easy to understand, even for first-time users. Perceptible information means information is available through multiple channels (visual, auditory, tactile) so it can be understood by people with different senses. Tolerance for error minimizes hazards and negative consequences of mistakes. Low physical effort aims for efficient operation with minimal fatigue. Size and space for approach and use ensures there is adequate room for people to approach, reach, and use the product, including those who use mobility devices.

The other options omit one or more of these principles or replace them with terms that aren’t part of the formal universal design framework, so they don’t capture the full set.
