Answer:
C. developed
Explanation:
Let's define each of the terms given:
- least developed: this refers to countries that are still in the stages of creating a stable government, flourishing economy, and scientific/technological advancements. Usually, this means that the GDP is quite low so standard of living is also low.
- underdeveloped: this is similar to least developed, just not as poor off as those countries. Underdeveloped countries are characterised by widespread poverty, so clearly, the standard of living will be quite low.
- developed: developed countries are those that have established a strong government, as well as cultivated advancements in technology, science, and the arts. These countries have high GDPs, so they do have a high standard of living.
- developing: these countries are usually called "low and middle income" countries because their economic situations are not as well off as those of developed countries. So, the standard of living here will definitely be worse than that of developed countries.
Thus, the answer is C.
