Correct Answer: vitamin D

Solution : The correct option is vitamin D.

Vitamin D, calcium, or phosphate deficiencies are the causes of rickets. Rickets, a disorder that impairs the healthy growth of bones and teeth, can result from a lack of any of these nutrients, including vitamin D, which is necessary for the intestines to absorb calcium and phosphate. More often seen in youngsters, rickets can cause bone abnormalities, stunted growth, and other associated symptoms.
