Correct answer: B — Bilateral Zanca-view shoulder radiographs if deformity is suspected

AC joint injury is common after a fall onto the shoulder point. Plain radiographs, including an AC-focused view, are appropriate when deformity or higher-grade injury is suspected. Advanced imaging is rarely the initial test unless another injury is suspected.
