Answer 1

The Correct Option is C

The most common type of anemia worldwide is Iron deficiency anemia. This condition occurs when the body lacks enough iron to produce hemoglobin, a protein in red blood cells responsible for transporting oxygen throughout the body. Iron deficiency anemia can result from factors such as insufficient iron intake, increased iron demand during pregnancy, or chronic blood loss, which can deplete the body's iron reserves.

Anemia Type	Characteristics
Sickle cell anemia	Genetic disorder; altered red blood cell shape
Thalassemia	Genetic disorder; abnormal hemoglobin production
Iron deficiency anemia	Due to low iron levels; common worldwide
Megaloblastic anemia	Due to vitamin B12 or folate deficiency
