Let’s understand this in a very simple way.

What is Vitamin B12?
Vitamin B12 is an essential vitamin needed for:

• Healthy red blood cells
• Proper nerve function
• DNA synthesis

Where do we get Vitamin B12 from?
Vitamin B12 is mainly found in:

• Meat
• Fish
• Eggs
• Milk and dairy products

👉 These are mostly animal-based foods.

In whom is Vitamin B12 deficiency rare?

✅ Correct Answer: (a) Non-vegetarians

Why non-vegetarians?
Because they regularly consume animal products that are rich sources of Vitamin B12.

👉 Therefore, Vitamin B12 deficiency is comparatively uncommon in them.

Why other options are not correct?

• (b) Strict vegetarians → ❌ Higher risk because B12 is mainly found in animal foods
• (c) Elderly → ❌ More prone due to reduced absorption of B12
• (d) None of the above → ❌ Incorrect because deficiency is rare in non-vegetarians

Important Nursing Point:
