Answer: (B)

The term 'dose' in the context of substance exposure specifically refers to the quantity of a substance that is absorbed into the body. This measurement is crucial for understanding the potential effects of the substance on an individual's health, as it allows practitioners to evaluate the relationship between exposure levels and adverse outcomes. The concept of dose takes into account not only the amount of the substance but also factors such as the route of exposure (inhalation, ingestion, dermal contact) and individual biological characteristics that influence how a substance is processed within the body. Understanding the dose is essential for risk assessment and determining safe exposure levels in various settings.
