Explanation
A. The result of legislative action: While politics influences legislative action, it is broader than just the outcome of laws. Politics involves the process of shaping policies and decisions.
B. The art of influencing others: Politics involves influencing decisions, policies, and resource allocation in society. In nursing and public health, advocacy and policy changes are achieved through political influence.

B. Tertiary prevention: Tertiary prevention focuses on managing existing health conditions, not preventing environmental injustices.
C. Environmental epidemiology: Environmental epidemiology studies the relationship between environmental exposures and health outcomes but does not directly advocate against environmental injustice.
