Correct Answer � A Explanation |

Clinical Features of Rickets (Vitamin D Deficiency in Children):
- Craniotabes (1): Softening of the skull, often the earliest sign in infants.
- Bossing of frontal and parietal bones (2): Enlarged, prominent skull bones due to defective mineralization.
- Muscle hypotonia (3): Hypocalcemia can lead to decreased muscle tone.
Why Not Statement 4?
- Shrinking of epiphysis at the lower end of the radius is incorrect. In rickets, widening of the growth plate and fraying are observed at the epiphysis due to defective endochondral ossification.
