Correct answer: D — Enuresis alarm

Enuresis alarm therapy is the most effective first-line treatment for primary nocturnal enuresis, with higher long-term cure rates than desmopressin. It requires motivation from the child and family and takes 2-3 months for effect. It works through conditioning the child to wake to bladder signals. Success rates are ~65-75%.
