Explanation:
Correct Option: B. Bigliani classified acromial morphology into three main types based on the supraspinatus outlet radiographic view. A Type III (hooked) acromion has a significantly higher correlation with subacromial impingement syndrome and full-thickness rotator cuff tears compared to flat (Type I) or curved (Type II) acromia.
