The Web Content Accessibility Guidelines (WCAG) provide standards to ensure websites are accessible to people with disabilities. They specifically address:

i. Text resizability (SC 1.4.4),

iii. Text alternatives for non-text content (SC 1.1.1),

iv. Keyboard accessibility (SC 2.1.1),

v. Device independence, which includes not relying solely on mouse input.

Visually appealing design (ii) is not an accessibility requirement and is thus not a WCAG focus. The correct answer is D: i, iii, iv & v are true; ii is false.

An informal usability review can be conducted by anyone, including stakeholders or developers, and does not require formal usability training or qualifications. It is typically subjective and based on general impressions. In contrast, an expert usability review (also called heuristic evaluation) is conducted by a trained usability expert who applies recognized usability principles. This is what differentiates the two approaches most clearly. Options A and C are misleading; expert reviews can be informal in format, and informal reviews aren't necessarily based solely on opinion. Option D is incorrect since both informal and expert reviews can be conducted individually or in groups.

A usability test participant is a person selected to represent the target user group and asked to perform specific tasks in a usability test. Their actions, reactions, and feedback help identify usability issues and evaluate the system’s effectiveness, efficiency, and user satisfaction. This role is strictly observational and does not involve organizing, observing, or setting up the test. Options A, B, and C describe other roles (e.g., technical support, observers, or moderators). Only option D accurately reflects the definition of a usability test participant.
