The Standards sur l'accessibilité du Web sets accessibility standards for which province?

The correct answer reflects that the Standards sur l'accessibilité du Web specifically applies to Quebec. This set of accessibility standards is formulated to ensure that web content is accessible to individuals with disabilities within that Canadian province. The significance of these standards lies in their alignment with Canadian laws and their commitment to promoting digital accessibility for all residents of Quebec, in accordance with the rights and inclusion principles upheld by various accessibility frameworks.

The other options pertain to different countries or regions that have their own accessibility standards or regulations, but they do not relate directly to the province of Quebec's specific framework. Each of those regions may have separate guidelines or laws intended to address accessibility, yet they wouldn't fall under the Standards sur l'accessibilité du Web that focus exclusively on the needs and regulations pertinent to Quebec. This highlights the localized nature of accessibility standards, which can vary significantly by region and jurisdiction.
