What was the new name for the competitive event category "I" in National HOSA?

The correct answer is "Health Science" because this term was adopted to better encapsulate the various fields and disciplines within health education and preparation that fall under the competitive events of HOSA. The renaming reflects a more comprehensive approach to health-related topics and aligns with the current focus of HOSA, emphasizing the importance of foundational health knowledge, skills, and competencies that individuals in the health profession should possess.

The other categories listed, such as "Health Professions" and "Emergency Preparedness," may refer to specific areas within HOSA's competitive events but do not represent the broader umbrella of disciplines covered by the new category "Health Science." "Teamwork" specifically refers to events that require collaborative efforts among team members but does not encompass the full scope of health science topics. Thus, "Health Science" is the most appropriate designation for the updated competitive event category.
