Which mineral deficiency causes abnormal blood cell development and bone demineralization?

Correct option is B

Ans. (b)
Sol. Copper deficiency can lead to abnormal blood cell development (such as anemia and neutropenia) and bone demineralization, which increases the risk of fractures. Copper plays a key role in iron metabolism, red blood cell formation, and bone health.
Explanation of each option:
· (a) Magnesium – Important for nerve and muscle function, but not directly related to red blood cell formation or bone structure.
· (b) Copper – Correct answer. Essential for hematopoiesis and bone strength.
· (c) Zinc – Important for immune function and wound healing, but not typically associated with bone demineralization.
· (d) Calcium – Critical for bone health, but its deficiency mainly causes osteoporosis, not abnormal blood cell development.
