B. Renin: An enzyme released by the kidney that initiates the RAAS cascade to regulate blood pressure and sodium balance; it does not directly increase RBC production.
C. Erythropoietin (EPO): A hormone produced mainly by the kidneys that stimulates the bone marrow to increase red blood cell production in response to hypoxia.
D. Aldosterone: Increases sodium reabsorption and potassium excretion in the kidney; it does not directly drive erythropoiesis.
