A
rate of erythrocyte production
B
rate of leukocyte production
C
rate of myloid production
D
rate of stem cell production
Explanation: 

Detailed explanation-1: -Erythropoietin (EPO) is a glycoprotein hormone, naturally produced by the peritubular cells of the kidney, that stimulates red blood cell production. Renal cortex peritubular cells produce most EPO in the human body. PO2 directly regulates EPO production. The lower the pO2, the greater the production of EPO.

Detailed explanation-2: -Erythropoietin is produced by interstitial fibroblasts in the kidney in close association with the peritubular capillary and proximal convoluted tubule.
