The ratio described in the question is called the relative risk. It is used to determine the extent to which an exposure increases the risk of a disease compared to the absence of that exposure.

Option B refers to the relationship between the amount or level of exposure to a substance or agent and its effect on health. Option D is a broader concept that refers to the establishment of a cause-and-effect relationship between an exposure and a disease, which requires additional evidence beyond the measurement of relative risk.
