The use of HTML tables for layout instead of proper semantic HTML and responsive design violates accessibility guidelines, particularly those defined in the Web Content Accessibility Guidelines (WCAG). Such a design makes it difficult or impossible for users relying on screen readers, keyboard navigation, or other assistive technologies to interact effectively with the site. Therefore, this creates a significant accessibility risk, which is distinct from general usability or user experience risks. Accessibility ensures inclusion of users with physical or cognitive impairments, making option B the correct choice.

A usability test plan is a foundational document created before conducting usability testing. It outlines the objectives, scope, methodology, participants, tasks, and schedule for the testing activities. One of its essential components is the schedule, which details when and how test sessions will occur to ensure proper resource allocation and time management. Including a schedule helps coordinate between test moderators, participants, observers, and stakeholders, making the testing process organized and efficient.

While briefing instructions (Option B) may be related to the usability test, they are typically documented separately or included in participant materials rather than the formal test plan itself. The test plan should be concise and focused; it need not be overly elaborate or lengthy (Option C), as clarity and usability of the plan are more important than length. The results of the test sessions (Option D) are not included in the test plan but rather compiled afterward in a test report or analysis document.

Therefore, the correct statement is that the usability test plan contains a schedule, ensuring a structured timeline for the usability testing activities.
