The correct answer is: If both the assertion and reason are true and reason is a correct explanation of the assertion.
The regulation of $\mathrm{RBC}$ production is accomplished by the hormone erythropoietin which is secreted by the juxtaglomerular cells of kidney. This hormone circulates to the red bone marrow, where it increases stem cell (myoblasts) mitosis and speeds the development of red blood cells
