Which symptoms are associated with vitamin D deficiency?

Vitamin D deficiency is closely associated with symptoms related to impaired bone health due to its crucial role in calcium and phosphate metabolism. Craniotabes is a condition noted in infants where the skull is softened, often due to inadequate mineralization which can result from vitamin D deficiency. Bowed legs, known as genu varum, is another classic manifestation, typically seen in rickets, which is a condition stemming from prolonged deficiency in vitamin D, leading to abnormal bone growth and mineralization. Additionally, delayed eruption of teeth can occur, reflecting the overall slowing of growth and development due to insufficient vitamin D.

These symptoms highlight the skeletal abnormalities and developmental delays that can arise, particularly in growing children, making option B the most relevant to vitamin D deficiency. The other options describe symptoms linked to different deficiencies or conditions not typically associated with vitamin D.
