Which of the following is a symbol associated with HOSA?

The caduceus is the correct symbol associated with HOSA, the Health Occupations Students of America. This emblem traditionally represents the medical profession and is often used to symbolize healthcare and healing. In the context of HOSA, the caduceus highlights the organization's focus on health-related education and careers, making it a fitting representation for an organization dedicated to preparing students for the healthcare field.

The apple, while sometimes associated with knowledge and education in general, is not specifically tied to health professions. The heart symbolizes care and compassion, which are essential in healthcare, but it does not specifically represent HOSA. The stethoscope is a common tool used by healthcare professionals, particularly in nursing and medicine, but it is not an official symbol of HOSA. Thus, the caduceus stands out as the most relevant and significant symbol for this organization.
