Which initiative is most likely to be sponsored by HOSA?

The annual health conference is most likely to be sponsored by HOSA because it aligns closely with the organization’s mission to promote health science education and prepare students for future careers in health professions. HOSA focuses on various aspects of health care, including education, awareness, and skill development, making a health conference a natural fit. Such conferences typically include workshops, keynote speakers from the health industry, and opportunities for networking among students, healthcare providers, and educators, all of which are central objectives of HOSA's initiatives.

The other options, while beneficial for a school or community, do not have a direct connection to the core objectives of HOSA. Career Day at local businesses could emphasize career exploration but is more about general job training and development rather than health science specifically. A school sports tournament and an art and music festival focus on extracurricular activities and the arts, which are generally outside the scope of HOSA’s health-focused goals. Thus, the annual health conference stands out as the most relevant initiative sponsored by HOSA.
