A{'text': 'Iodine'}
B{'text': 'Calcium'}
C{'text': 'Sodium'}
D{'text': 'Iron'}
Answer & Solution
Correct answer: D. {'text': 'Iron'}
1. Anaemia means a low haemoglobin level in the blood.
2. Haemoglobin requires **Iron** to form, so iron deficiency reduces haemoglobin.
3. Iodine deficiency causes goitre; calcium deficiency weakens bones.
4. Sodium deficiency is unrelated to anaemia.
5. Hence the deficient nutrient is **Iron**.
