Question

Quizplus · Accepted Answer

Rickets is caused by a deficiency of vitamin D₃, which is necessary for the absorption of calcium and phosphorus in the body. Without vitamin D₃, bones become soft and weak, leading to deformities and fractures. Vitamin A is not directly involved in bone development, while growth hormone and thyroid hormone play important roles in growth and development but do not cause rickets if deficient. Vitamin C deficiency can lead to scurvy, which affects the connective tissue in the body, but not necessarily the bones.
