Correct answer
Explanation

Confounding occurs when a factor is related to both the exposure and the outcome, leading to a distorted association between the two. In the given example, age is a confounding factor because it is related to both smoking and lung cancer. Smokers are more likely to be older than non-smokers, and older people are more likely to develop lung cancer. Therefore, not controlling for age in the study could lead to an overestimation of the association between smoking and lung cancer.
