Which term describes the social integration within a network of relationships?

The correct term to describe the social integration within a network of relationships is "social cohesion." Social cohesion refers to the bonds that bring people together within a society and the level of connectedness and solidarity among group members. This concept emphasizes the importance of relationships and interactions that create a sense of belonging, trust, and mutual support among individuals within a specific social network.

While "social network" refers specifically to the structure of relationships and connections among individuals or groups, it does not inherently capture the aspect of integration and solidarity that "social cohesion" embodies. "Social fabric" alludes to the underlying values and norms that connect individuals in society, but it does not focus solely on the relational aspect. Meanwhile, "social system" refers to the organized patterns of relationships and institutions within a society, which can include social networks but is a broader term that encompasses various social structures, including legal, economic, and political frameworks.

Thus, "social cohesion" effectively highlights the integration achieved through interpersonal relationships within a network, making it the most fitting choice for the question.
