Correct answer: A — Hip ultrasound and referral for paediatric orthopaedic management

Positive Ortolani and breech risk suggest developmental dysplasia of the hip, and early ultrasound/referral allows harness treatment. Waiting until walking age risks late dislocation and surgery. CT is generally avoided as first-line imaging in young infants because ultrasound is effective and avoids radiation.
