Selective serotonin inhibitors (B) are used for treating depression and anxiety, not endometriosis. Dopamine agonists (C) are used for conditions like Parkinson's disease and hyperprolactinemia, not endometriosis. Bisphosphonates (D) are used to treat osteoporosis, not endometriosis. Therefore, oral contraceptives are the most appropriate medication to discuss with a patient diagnosed with endometriosis.
