Incidence rate refers to the number of new cases of a specific disease or condition in a particular population during a specific time period. It is expressed as a rate per specified population, usually with a denominator of 1000 or 100,000. Incidence rate is thus related to the prevalence of a disease in a population, but whereas prevalence is a measure of how many people in a population have a particular disease or condition at a given time, incidence rate is a measure of how many people in a population develop a particular disease or condition over a specified period. Option A is the closest definition.
