According to Piaget,Marge has achieved __________ of baseball information.

A) disequilibrium
B) organization
C) object permanence
D) a secondary circular reaction

Organization is the cognitive process of arranging and grouping information into a coherent and meaningful system. In this scenario, Marge has undergone the process of gradually organizing her understanding of baseball by incorporating new information and skills. She has developed a functional cognitive system for playing baseball, suggesting that she has achieved organization of baseball information. The other options (disequilibrium, object permanence, and a secondary circular reaction) are not relevant to this scenario.
