What idea does the Healthy Communities and Cities initiative support?

A. The World Health Organization (WHO) is the city's primary information source: WHO supports the initiative but is not the city’s main information source. B. Healthy public policy is the responsibility of elected officials: Public policy is a shared responsibility- this option limits it to elected officials. C. Healthy cities and communities must be both environmentally and socially sustainable: This is a core belief of the initiative- emphasizing holistic, sustainable development for long-term health. D. Physical environments cannot be changed, thus, strategies must be developed in order to cope with them: Contradicts the initiative’s belief that environments can and should be improved for better health outcomes.
