Ans: A
Feedback:
Blood cell production takes place exclusively in red bone marrow, which predominates in infants and decreases (but not disappears) with age. Yellow bone marrow is composed primarily of adipose tissue and is not hematopoietically active. As the need for RBC production decreases during postnatal life, red marrow is gradually replaced with yellow bone marrow in most of the bones. In adults, red marrow persists in the vertebrae, ribs, sternum, and ilea.
