The correct option is A Cross-cutting
The population in Belgium is divided into three linguistic communities: Dutch, French, and German. This led to social division.
However, the government took actions that made a series of constitutional reforms. As a result, the Belgian cabinet represents all the ethnic groups equally. Once people get political representation, they can then address their social and economic issues. This halted all social tensions in the country.
This is an example of cross-cutting social differences.
