The question of economic growth is thrown into further confusion by the methods used to measure it. Fundamentally, economics is myopic. It measures reality by its current market price. The intrinsic value of real things, their essential character which remains unchanged even when their price on the market fluctuates, is not an issue to the economist. He is like Oscar Wild's cynic.
Someone who knows the price of everything and value of nothing
The most important words in the paragraph are "price” and "value”. Essentially, the author wants to convey that the economists fail to draw a relationship between the price and the value of real things. Option (a) can be eliminated because it is outside the scope of the passage. Options (c) and (d) do not fit in with the idea of a cynic and hence can be eliminated. Option (b) however, talks about the entire essence of the paragraph in brief and blends with the flow of the paragraph.
Therefore, option (b) is the correct answer choice.
