Correct answer: C — Mediastinal shift to right (left tension pneumothorax)

Absent BS left + hyperresonance + high pressures in ventilated NEC neonate = left tension pneumothorax. Mediastinal shift to right with tracheal deviation. Common complication: abdominal distension → diaphragmatic splinting → high pressures. Needle decompression then chest drain.
