In the context of any country, which one of the following would be considered as part of its social capital?

Option (D) is correct because social capital refers to the internal social and cultural coherence of a society, specifically the networks, norms, and mutual trust that facilitate coordination and cooperation for mutual benefit. Option (A) is the most tempting distractor but actually represents human capital, which focuses on individual skills, education, and productivity rather than collective social bonds. The core concept being tested is the distinction between social capital (relational assets) and human or physical capital (individual or material assets).
