What is the focus of Article 11 in the Arizona Constitution?

The correct choice highlights that Article 11 of the Arizona Constitution specifically addresses the establishment and governance of the state's universities. This article outlines the framework for Arizona's higher education system, detailing the responsibilities and functions of the Board of Regents, which oversees public universities. It emphasizes the importance of education within the state and provides guidelines for the administration of state-supported institutions, ensuring structural organization and accountability in higher education.

The other options, while related to various aspects of governance and policy, do not pertain directly to the core subject of Article 11. For instance, trade and commerce are typically covered under different sections of the constitution that focus on economic regulations. The rights of students and educators also fall outside the main focus of this article, as it centers more on governance rather than individual rights. Finally, state taxation policies would generally be found in articles focused on fiscal regulations and budget management, which are distinct from educational governance.
