Final answer:
Kim finds the greatest amount of social disorganization in the Zone of Transition (Zone B), which is characterized by a mix of commercial and residential properties and high population turnover.
Step-by-step explanation:
According to the concentric zone model developed by Ernest Burgess, the greatest amount of social disorganization is often found in the Zone of Transition. This area is known as Zone B and it typically surrounds the central business district (Zone A). In Zone B, one can find formerly wealthy homes that have been divided into cheap apartments for new immigrant populations, small manufacturers, pawn shops, and other marginal businesses. This zone is characterized by high population turnover and a mix of commercial and residential property, often in a state of dilapidation or transition, contributing to a higher degree of social disorganization.
