Explanation:

- Bronislaw Malinowski emphasized the importance of reciprocity and exchange in building relationships between individuals and groups.

- These processes help in creating social ties and networks, essential for living together in a community.

- Accomodation (Option 1): This means adapting or compromising but is not the main result of reciprocity and exchange according to Malinowski.

- Adjustment (Option 2): This means changing or adapting to fit new conditions, which happens but is not the focus here.

- Integration (Option 3): This is the process of bringing individuals or groups together, but it's broader than what Malinowski suggested about exchange.

- Cooperation (Option 4): This is the correct answer. Malinowski believed that reciprocity and exchange foster cooperation, as they encourage mutual support and shared understanding.
