Which of the following deficiencies causes beriberi?

Thaimine

The correct answer is Option (1) – Thaimine

Optical neuropathy, Wernicke-Korsakoff syndrome, and beriberi are all caused by a vitamin B (thiamine) deficiency.

It is a  neurological and cardiovascular condition. Wet beriberi, dry beriberi, and infantile beriberi are the three main types of the condition.

While Wet beriberi is associated with mental confusion, muscle atrophy, and edoema, Dry beriberi is primarily defined by muscular dysfunctions.

Infants breastfed by mothers who are thiamin deficient can develop infantile beriberi.
