Answer 1

The Correct Option is D

Step 1: Understanding rickets.
Rickets is a childhood bone disorder where bones soften and weaken due to impaired mineralization of growing bones. It commonly leads to bowed legs and skeletal deformities.

Step 2: Role of Vitamin D.
Vitamin D is essential for calcium and phosphorus absorption from the intestine. Its deficiency reduces bone mineralization, leading to rickets.

Step 3: Eliminating wrong options.
- (1) Vitamin A: Deficiency causes night blindness, not rickets.
- (2) Vitamin B: Deficiency causes beriberi, pellagra, etc., but not rickets.
- (3) Vitamin C: Deficiency causes scurvy, not rickets.
- (4) Vitamin D: Correct, deficiency causes rickets.

Step 4: Conclusion.
Thus, rickets in children are caused by deficiency of Vitamin D.

Final Answer: \[ \boxed{\text{Rickets is caused by deficiency of Vitamin D.}} \]
