A city began treating its sewage with a new chemical product that was designed to help break down solid waste. Once solid wastes were broken down by the chemical product, the city planned to pump the treated water into a river that the city used as a drinking water source. The chemical product had only been on the market for two years and there were only a few scientific studies that assessed the potential harm to human and environmental health. However, the few scientific studies that had been completed found that the chemical product had caused cancerous cells to grow in mice. The scientists explained that this same reaction could occur in humans if the product was ingested in water. Which of the following statements accurately explains the relationship between risk and uncertainty in this scenario?
a. The scenario presents a low level of risk and a high level of uncertainty.
b. The scenario presents a low level of risk and a low level of uncertainty.
c. The scenario presents a low level of risk and a low level of uncertainty.
d. The scenario presents a high level of risk and a high level of uncertainty.
