Ruth, an Infant, Sucked Everything That Touched Her Lips and Also

Ruth, an infant, sucked everything that touched her lips and also sucked nearby objects. A few months later, she learned that certain objects such as her mother's breasts or a milk bottle can be sucked but other objects such as spoons, her toys, or her blanket cannot be sucked. In the context of Jean Piaget's theory of infant development, the cognitive processes most likely responsible for Ruth's actions are

A) coordination and internalization.
B) equilibration and organization.
C) assimilation and accommodation.
D) habituation and dishabituation.
