Final Answer : C, Explanation :  Relative risk is a measure of the risk of a certain event happening in one group compared to the risk of the same event happening in another group. In this context, a relative risk of 23.0 for lung cancer death means Wendi is about 23 times more likely to die of lung cancer than those who do not smoke. This does not directly compare lung cancer risk to heart disease risk, nor does it compare her risk to a twin sister's risk for heart disease.
