Question

Which one of the following pairs is not correctly matched ?

• A. Vitamin B₆ – Loss of appetite
• B. Vitamin B₁ – Beri-beri
• C. Vitamin B₂ – Pellagra
• D. Vitamin B₁₂ – Pernicious annemia

Answer 1

The Correct Option is C

To determine which pair is not correctly matched, we need to understand the diseases associated with each vitamin mentioned. Let’s evaluate each pair:

1. Vitamin B₆ – Loss of appetite: Vitamin B₆ is known to play a role in creating neurotransmitters and red blood cells. A deficiency may lead to symptoms like irritability, confusion, and in some cases, a loss of appetite.
2. Vitamin B₁ – Beri-beri: This is correctly matched. Vitamin B₁, also known as thiamine, is crucial for energy metabolism. Its deficiency leads to Beri-beri, which affects the cardiovascular and nervous systems.
3. Vitamin B₂ – Pellagra: This pair is not correctly matched. Pellagra is caused by a deficiency of niacin (Vitamin B₃), not Vitamin B₂. Vitamin B₂, also known as riboflavin, deficiency leads to conditions like ariboflavinosis, which can cause sore throat, lesions on the lips and corners of the mouth, and inflammation of the tongue.
4. Vitamin B₁₂ – Pernicious anemia: This is correctly matched. Vitamin B₁₂ deficiency can lead to pernicious anemia, which is a condition where the body can't make enough healthy red blood cells due to lack of Vitamin B₁₂.

Thus, the correct answer is that the mismatched pair is:

Vitamin B₂ – Pellagra

This pair incorrectly associates Vitamin B₂ with pellagra, which is actually related to a deficiency in Vitamin B₃ (niacin).
