Your answer: —  Â·  Correct: B
Explanation

Rickets is a condition characterized by the softening and weakening of bones in children, primarily caused by a prolonged deficiency of Vitamin D. Vitamin D is essential for the body to effectively absorb calcium and phosphorus from the diet, which are critical for bone mineralization and growth [3]. Without sufficient Vitamin D, intestinal calcium absorption drops significantly, leading to skeletal deformities and growth failure [3]. Environmental factors like heavy smog can also contribute to rickets by decreasing natural Vitamin D production from ultraviolet radiation. While other deficiencies cause distinct issues—such as Vitamin C leading to scurvy, Vitamin A causing night blindness, and Vitamin B deficiencies resulting in conditions like beriberi or anemia [1]—rickets is specifically linked to the Vitamin D-calcium axis [2].
