Question

Deficiency of which of the following vitamins causes the disease 'Rickets' in children?

• A. Vitamin A
• B. Vitamin B1
• C. Vitamin C
• D. Vitamin D

Hint:

Important Vitamin Deficiencies: Vitamin A \(\rightarrow\) Night Blindness Vitamin B1 \(\rightarrow\) Beri-Beri Vitamin C \(\rightarrow\) Scurvy Vitamin D \(\rightarrow\) Rickets

Answer 1

The Correct Option is D

Step 1: Understand Rickets.
Rickets is a disease in children where bones become soft and bend. We need the vitamin whose lack causes it.

Step 2: Role of Vitamin D.
Vitamin D helps the body absorb calcium and phosphorus, which harden the bones.

Step 3: The link.
Without enough Vitamin D, calcium is poorly absorbed and bones stay weak. This leads to Rickets, with signs like bowed legs.

Step 4: Rule out others.
Vitamin A lack causes night blindness. Vitamin B1 lack causes beri-beri. Vitamin C lack causes scurvy.

Step 5: Conclude.
Rickets is caused by deficiency of Vitamin D.

Answer: Vitamin D
