When a customer emphasizes the importance of accessibility, it means they are concerned with ensuring that users with disabilities or limitations are not excluded from using their products or services. Accessibility is about inclusiveness—providing equal access and opportunity to all users regardless of physical or cognitive ability. Option C directly reflects this understanding. The other options (A, B, and D) are aspects of usability or development methodologies but do not relate to addressing the needs of users with disabilities, which is the core focus of accessibility.

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.
