Which of these is not a potential source in your community for biological agents?

Auto manufacturing plants typically focus on the production and assembly of vehicles and related components, making them less likely to be involved with biological agents. In contrast, hospitals routinely deal with pathogens and medical waste, laboratories are directly involved in the research and development of biological materials, and agricultural fields can be sources of both natural and engineered pathogens, as they often involve crops and livestock. Each of these other options has direct connections to environments where biological agents may originate or be handled, which makes auto manufacturing plants distinctly separate from these potential sources.
