Correct answer: C — Laparotomy for manual reduction

When non-operative reduction of intussusception fails (usually after up to 3 attempts, depending on institutional protocol), surgical intervention is required. Laparotomy (or laparoscopy) with manual reduction or resection of non-viable bowel is indicated. Delay increases the risk of bowel necrosis.
