Answer:
Explanation:The common trait among developed nations is a high per-capita income.
### Explanation:
**Option C: A high per-capita income**
Developed nations are characterized by high levels of income per person. This economic prosperity is reflected in a high standard of living, better healthcare, advanced infrastructure, and extensive educational opportunities. High per-capita income allows for greater consumer spending and investment, which further supports the economy and improves overall quality of life.
### Other Options:
**Option A: A multicultural society**
While many developed nations do have multicultural societies, this is not a universal trait. Some developed countries are relatively homogenous in terms of culture and ethnicity.
**Option B: A national language**
Having a national language is common in many countries, both developed and developing. It is not a distinguishing trait of developed nations.
**Option D: A highly agricultural society**
Developed nations typically have diverse economies with a strong emphasis on industrial and service sectors rather than being highly agricultural. Agriculture tends to play a smaller role in the overall economy of developed countries.
Thus, the most accurate answer is **C: A high per-capita income**.
