Deficiency of iron causes.

Correct option is B

The correct answer is:(B) Anemia

Explanation:
A deficiency of iron in the diet leads to anemia, a condition in which the body does not have enough healthy red blood cells to carry adequate oxygen to the body's tissues. Iron is a crucial component of hemoglobin, the protein in red blood cells that binds to oxygen. A lack of iron leads to reduced hemoglobin levels, causing fatigue, weakness, and other symptoms.

Information Booster:
• Iron is essential for the production of hemoglobin in red blood cells.
• Iron deficiency anemia is one of the most common types of anemia, particularly in women and children.
• Symptoms of anemia include fatigue, paleness, shortness of breath, and dizziness.
• The condition can be treated by increasing iron intake through diet (e.g., leafy vegetables, meat, beans) or iron supplements.
• Iron-deficiency anemia is diagnosed by blood tests measuring hemoglobin and ferritin levels.

Additional Information:
•  Goiter: Goiter is caused by a deficiency of iodine, not iron. It leads to an enlargement of the thyroid gland.
• Rickets: Rickets is caused by a deficiency of vitamin D, calcium, or phosphate, leading to weak bones.
•  Scurvy: Scurvy is caused by a deficiency of vitamin C, leading to bleeding gums and skin problems.
