Which statement is true about enuresis?

Rationale: A. Most children do not achieve spontaneous resolution of enuresis by age 4; it is more common for spontaneous resolution to occur gradually over time, often by age 6–7 years. B. Bedwetting alarms and behavioral therapy are effective first-line interventions for enuresis, helping children recognize bladder fullness and establish bladder control. C. Nighttime (nocturnal) enuresis is more common than daytime (diurnal) enuresis in children. D. Enuresis is usually a normal developmental variation and does not typically indicate an underlying disease in otherwise healthy children; extensive urological workup is not routinely required unless other concerning symptoms are present.
