What must be prescribed by the Council regarding regulated members?

The correct answer is based on the Council's role in overseeing and regulating the standards and practices of its members. Specifically, the Council has the authority to set categories and criteria for enrollment of regulated members. This ensures that professionals entering the field meet specific qualifications and standards vital for maintaining the integrity and quality of the profession. By establishing these criteria, the Council ensures that all members possess the necessary knowledge, skills, and competencies required to practice safely and effectively, thus protecting the public interest.

In contrast, the development of marketing strategies, scheduling of meetings, and the selection process for public members, while important, do not fall under the Council's mandate concerning the regulation of members' enrollment. These aspects are more related to administrative or governance functions rather than the core responsibilities of defining who qualifies as a regulated member.
