Conservation in child development specifically refers to the understanding that certain properties of objects, such as volume, mass, and number, remain unchanged even when their appearance is altered. This cognitive ability typically develops during the concrete operational stage, which occurs between ages 7 and 11, according to Piaget's theory of cognitive development.

Children who have achieved conservation can recognize, for example, that when water is poured from a short wide glass into a tall thin glass, the amount of water remains the same despite the change in shape. This understanding is essential for grasping more advanced mathematical concepts and critical thinking skills later in life.

The other options address different aspects of child development, such as independence (related to self-help skills), understanding of time (which pertains to temporal awareness), and forming emotional relationships (linked to social and emotional development). However, none of these options pertain specifically to the concept of conservation, which focuses on the continuity of certain properties regardless of physical transformation.
