      I think it could be relative risk.  85% more risk indicates 1.85 times the risk.  Thus a smoker would have 1.85 times the risk of developing a lung cancer as compared to a non-smoker.

        Then the question is not correctly framed. or there are not enough range of choices in the answers.
         
        It may be either Attributable risk or Population attributable risk.

          ya rightly stated that the question is from Leon Gordis....page no 222, Q1.......but the question in Gordis is slightly different.......It doesn't have the word "more" in it and just states that 85% cases of lung cancer is due to cigarette smoking..........still the answer should be attributable risk........as the AR is a measure of the effect that can be attributed to a specific exposure.........

            Sorry, I dont seem to agree with Attributable Risk as far as the framing of the question and the language is concerned. See, the terms revolve around an almost similar context but the perspective is different for each term and I still think that RR is the appropriate choice! Can somebody justify AR in the language in which the question is framed?

              also to call it is a relative risk, the control group should be specified clearly.
