Answer:
c. Object permanence
Explanation:
Object permanence is a psychological theory about the permanence of an object even if it is hidden through mental representation. The object exists even when it is not seen, touched, smelled etc. The Object permanence signals transition from sensorimotor stage of development to the preoperational stage in a child.
Jean Piaget studied Child's Cognitive development in which she explored children's social and mental capacities and a proposed theory of Object Permanence. She discovered that an infant's most important accomplishment is the ability to comprehend the surrounding in his sensorimotor stage, lasting up to 2 years of age since birth.
An infant watches a toy car go behind a screen presumably hiding a block and then staring at it after it emerges on the other side is an example of Object permanence .
