Correct: A — the proportion or amount of disease incidence (or risk) that is attributable to a specific exposure. Attributable risk is the excess incidence among the exposed that would be eliminated if the exposure were removed — in its absolute form the risk difference, incidence in the exposed minus incidence in the unexposed, and in its proportional form the attributable fraction. It is the measure of public-health impact, as against the relative risk, which measures the strength of association and is what option C describes. Option B confuses it with proportionate mortality, and option D describes no recognised measure.
