What are the main stages of child development?

The main stages of child development are accurately represented by the choice of Prenatal, Infancy, Early Childhood, Middle Childhood, and Adolescence. This option correctly outlines the comprehensive lifespan stages associated with child development from conception through adolescence.

Prenatal development, which occurs before birth, is a critical period where significant physical and neurological growth happens. Infancy follows, marked by rapid development in motor skills, cognitive abilities, and emotional bonding. Early Childhood includes the preschool years, wherein social interactions and foundational learning are paramount. Middle Childhood encompasses the school-age years, where cognitive skills and peer relationships become increasingly important. Finally, Adolescence marks the transition into adulthood, characterized by further physical development and identity formation.

The other options either miss certain stages or include periods that do not specifically pertain to child development as traditionally defined. For instance, including "Old Age" or "Adulthood" in stages intended for child development does not align with the typical framework used in child development studies.
