Which cognitive developmental milestone is characteristic of preschoolers?

Choice A rationale Preschoolers, typically aged 3 to 5 years, are often quite fearful of bodily injury and pain, which stems from their magical thinking and limited understanding of body integrity and cause-and-effect regarding the body. This fear is a major developmental characteristic and is often observed during medical procedures, making this statement scientifically incorrect. Choice B rationale The most rapid and significant growth during the preschool years occurs primarily in the frontal lobes of the brain. The frontal lobes are responsible for higher-level cognitive functions such as planning, organizing, sustained attention, and impulse control, which explains the gradual maturation of these skills during the preschool period. Choice C rationale Preschoolers demonstrate a rudimentary and developing understanding of cause and effect relationships, particularly for concrete, observable events they experience. For example, they understand that pushing a toy car makes it roll. This development moves beyond the sensorimotor stage and is a key cognitive milestone for this age group. Choice D rationale Preschoolers, operating within Piaget's Preoperational stage, are usually capable of classifying objects according to a single attribute, such as size, color, or shape, by the end of the preschool period. While their classification skills are limited and non-reversible, they are certainly not unable to classify objects by size. —.
