5. A study is planned to assess the effectiveness of a new combination drug for treating nephrolithiasis (kidney stone). One hundred patients with nephrolithiasis will be randomly assigned to receive either the new combination drug or the standard surgical intervention. The efficacy of the new drug will be measured by the time it takes a patient to return to normal activities, measured in days. Identify the appropriate research design for this study a. Prospective cohort study b. Randomized controlled trial c. Case control study d. Retrospective cohort study 6.
