Which of the following is NOT one of the components of the Intervention Wheel?

• A. Population base, levels of practice, and public health interventions.
• B. Interventions, color wedges, and levels of practice.
• C. Communities, systems, and individuals/families.
• D. Populations at risk, populations of interest, and levels of practice.

Answer: (B)

The Intervention Wheel is built around three real components: the public health interventions themselves (the 17 categories), the levels of practice (individuals/families, communities, systems), and the population-based approach (targeting populations at risk or of interest). The option that mentions color wedges is describing a visual design feature of how the wheel is drawn, not a separate substantive component of the framework. Interventions and levels of practice are genuine components, and the population-based aspect is essential, whereas color wedges are just a way to organize or display information. So that option is not a true component of the Wheel.
