Correct Answer: B

❌A) INCORRECT: There is no evidence of a fracture line or displacement at the surgical neck of the humerus. The cortical margins of the proximal humerus appear intact.

✅B) CORRECT: The radiograph demonstrates a small, dense calcific deposit at the lateral aspect of the greater tuberosity of the humeral head. This finding is common in middle-aged females and corresponds with the patient's demographics and presentation with shoulder pain.

❌C) INCORRECT: The acromioclavicular joint appears intact without separation or superior displacement of the distal clavicle relative to the acromion.

❌D) INCORRECT: The humeral head is appropriately positioned within the glenoid fossa. There is no evidence of posterior dislocation. The glenohumeral joint maintains normal anatomic alignment, without features suggesting posterior dislocation—such as the "light bulb" sign, which may present as an abnormally symmetric, rounded appearance of the humeral head on AP projection in some cases of posterior dislocation.
