Conservation of liquid quantity is mastered during which Piagetian stage?
- A
Sensorimotor (0–2 years)
- B
Preoperational (2–7 years)
- Ccheck_circle
Concrete operational (~7–11 years)
- D
Formal operational (11+ years)
Explanation
Concrete-operational children grasp conservation of mass, volume, and number — pre-operational kids fail because they centrate on one dimension (height of liquid).
