Use of polished rice in human diet causes following diseases

1. A

   Rickets

   (a) Rickets. Rickets is vitamin D (and calcium/phosphate) deficiency in children, not polished-rice beriberi.

2. B

   Anemia

   (b) Anemia. Iron, B12 or folate lack; not the classic polished-rice disease.

3. C

   Goitre

   (c) Goitre. Iodine deficiency; unrelated to rice polishing.

4. D

   Beriberi

   (d) Beriberi. Polishing rice strips the bran that holds thiamine (vitamin B1). Thiamine deficiency causes beriberi. That is the official key.

Summary. Official key is (d). A polished-rice diet causes beriberi (thiamine deficiency). Rickets, anaemia and goitre map to other deficits.
