Detailed Solution
(b) is correct: beri-beri is a deficiency disease caused by the lack of thiamine (vitamin $B_1$), which is needed as a coenzyme in carbohydrate metabolism.
(d) is correct: it occurs mainly where the staple diet is polished rice, because thiamine is present in the husk and outer layers of the grain, which are removed in polishing.
(e) is correct: the symptoms include pain due to neuritis, paralysis, muscle wasting, progressive oedema, mental deterioration and finally heart failure.
(a) is not correct: beri-beri is not a disease specific to sub-Saharan Africa.
(c) is not correct: a disorder in infants and children due to protein deficiency describes kwashiorkor, not beri-beri.
So the group containing all three correct statements is b, d and e.
(d) is correct: it occurs mainly where the staple diet is polished rice, because thiamine is present in the husk and outer layers of the grain, which are removed in polishing.
