Correct answer: C — Intussusception

Episodic colicky pain with leg drawing, pallor, lethargy between episodes, redcurrant jelly stool (late sign), and a sausage-shaped abdominal mass is classic intussusception, most commonly ileocolic. Air enema reduction is the first-line treatment; surgery is required if reduction fails or peritonitis is suspected.
