Assimilation is to accommodation as

A) genetic is to environmental.
B) Piaget is to Freud.
C) cognitive is to social.
D) incorporating is to adjusting.

Assimilation and accommodation are two of Jean Piaget's cognitive development concepts. Assimilation refers to the process of incorporating new information into existing mental schemas, whereas accommodation involves adjusting existing schemas to fit the new information. Therefore, the best choice for the analogy is D, where incorporating is to adjusting. Options A and B are not related to the concept of assimilation and accommodation, and option C is too vague to be a valid option for this analogy.
