Jamar's understanding of conservation and ability to classify objects into hierarchies of classes and subclasses indicates that he is in the concrete operational stage of cognitive development, which typically occurs between ages 7 and 12. The sensorimotor stage (A) occurs from birth to age 2 and is characterized by the development of basic sensory and motor skills. The preoperational stage (B) occurs from ages 2 to 7 and is marked by egocentrism and the emergence of symbolic thought. The sociocultural stage (D) is not a recognized stage of Piaget's theory of cognitive development.
