The correct answer is b. Case-control study.<br /><br />In a case-control study, participants are selected based on whether they have the outcome of interest (in this case, breast cancer) or not. The researchers then look back in time to compare the exposure (prior use of oral contraceptives) between the cases (women with breast cancer) and the controls (comparable group of women without breast cancer). This design is appropriate for studying the association between cancer and steroid hormone use, as it allows for the comparison of exposure between cases and controls.
