Correct Option (B)
The passage indicates that detractors of democracy, particularly those influenced by the East Asian experience of the 1970s and 1980s, perceived a serious tension between democracy and development because several countries successfully achieved significant economic growth without adopting a democratic system of governance. This demonstrated that economic progress was not necessarily contingent upon democratic institutions, leading to the argument that one might have to choose between democracy and development.
Incorrect Options:
Option (A) states that democracy and development are distinct and separate goals. While the passage notes that "champions of democracy" have tended to see them as distinctly separate goals, this observation alone is not presented as the primary reason why detractors perceive a "serious tension." The tension, as described for detractors, arises from the perceived ability to achieve development without democracy.
Option (C) claims that non-democratic regimes deliver economic growth faster and far more successfully than democratic ones. The passage mentions that "several of these countries were immensely successful" in promoting economic growth without democracy. However, it does not make a universal claim that non-democratic regimes are always or inherently faster and far more successful than democratic ones. The statement in the option is an overgeneralization not fully supported by the passage's specific context.
