Correct answer: B — Justified periapical radiograph with dose optimisation

When clinically justified, dental radiographs can be taken during pregnancy using dose optimisation and appropriate technique; untreated infection also carries risk. Delaying necessary imaging despite spreading infection can compromise care. The pearl is that pregnancy changes justification discussions, but it is not a blanket contraindication to necessary dental imaging.
