Which of the following is a risk factor for ovarian cancer?

Explanation:
Genetic predisposition plays a major role in ovarian cancer risk, and a BRCA1 gene mutation markedly increases that risk because BRCA1 is essential for repairing DNA damage; when its function is lost, cells accumulate mutations that can lead to cancer. This makes BRCA1 mutation the strongest risk factor among the options. By contrast, regular exercise is beneficial for health but not a cancer risk factor; long-term oral contraceptive use actually lowers ovarian cancer risk; and benign ovarian cysts are common and not associated with a higher risk of ovarian cancer.
