Which deficiency leads to Beriberi?

Vitamin B12
Vitamin B3
Vitamin B1
Vitamin B9

The correct answer is: Vitamin B1

Beriberi is a condition that results from a deficiency in Vitamin B1, also known as thiamine. Thiamine is essential for the metabolism of carbohydrates and plays a crucial role in the proper functioning of the nervous system. Symptoms of beriberi can include weakness, fatigue, nerve damage, and in severe cases, heart failure. Vitamin B12 deficiency can lead to pernicious anemia and neurological problems. Vitamin B3 deficiency can cause pellagra, characterized by the "4 D's": diarrhea, dermatitis, dementia, and death if left untreated. Vitamin B9, also known as folic acid, is crucial for cell division and is important for preventing neural tube defects in developing fetuses.
