B)one week.

D)four months.

Accepted Answer

The typical life span of a red blood cell is around 120 days or four months, during which they transport oxygen from the lungs to the body tissues and carbon dioxide from the body tissues to the lungs for removal. After the red blood cells die, they are removed from circulation and their components, such as iron, are recycled in the body.
