Matching diseases to nutrient deficiencies: iron, vitamin C, vitamin D

Steps:

• Anaemia results from iron deficiency in the diet.
• Scurvy results from vitamin C deficiency.
• Rickets results from vitamin D deficiency.
• Option D orders them as anaemia, scurvy, rickets, aligning with iron, vitamin C, vitamin D.

Why D is correct:

• It matches the standard sequence of deficiencies: iron causes anaemia, vitamin C causes scurvy, vitamin D causes rickets.

Why the others are wrong:

• A: Starts with scurvy (vitamin C), mismatching iron deficiency.
• B: Places rickets (vitamin D) before scurvy (vitamin C), incorrect sequence.
• C: Begins with scurvy (vitamin C) instead of anaemia (iron), wrong order.

Final answer: D
