Correct answer: C — Small field-of-view CBCT if it changes management

When conventional periapical radiographs are inconclusive and the result would affect treatment, a limited field-of-view CBCT can help assess suspected vertical root fracture. A panoramic radiograph is less sensitive for fine root defects. The pearl is to balance diagnostic value against radiation dose and use a focused field when advanced imaging is justified.
