The best choice is B, dose-response assessment. This type of assessment examines the relationship between the dose of a chemical and the response (toxicity) it produces. In this case, the researchers want to examine the effects of different concentrations of the carcinogen on mice, which is a dose-response assessment. Exposure assessment (choice A) involves determining the amount, frequency, and duration of exposure to a chemical in a population. Hazard assessment (choice C) involves determining the types and levels of adverse effects a chemical may cause. Risk characterization (choice D) involves integrating information from the exposure assessment, hazard assessment, and dose-response assessment to estimate the likelihood and severity of harm to humans or other organisms.
