Final Answer : C, Explanation :  The external validity of a study refers to the extent to which its findings can be generalized to broader populations. Conducting a political survey exclusively among women could limit the generalizability of the results to the entire population, which includes both men and women, thus casting doubt on the external validity of the study.
