The Correct Option is C

Solution and Explanation

To determine the exact age of a child based on an X-ray of the wrist, radiologists use the presence and maturity of specific growth plate features in the bones. The key landmarks include the ossification centers in the carpal bones and the maturity of the distal radius and ulna growth plates.

Identification Process:

  1. Carpal Bones Development: At around 6 years, most children exhibit a specific pattern of ossification in the carpal bones. The capitate and hamate bones are usually visible by the age of 2, while additional carpal bones begin to appear between ages 3 to 6.
  2. Growth Plate Analysis: The epiphyseal plates or growth plates of the distal radius and ulna also provide clues. By 6 years, these growth plates exhibit certain development changes that radiologists are trained to identify.

Based on this age assessment methodology, the provided wrist X-ray most likely corresponds to a developmental stage consistent with a 6-year-old child, as the other options (2 years or 9 years) would show distinctly different ossification patterns and growth plate developments.
