Answer:
C) The second approach, because it takes into account the relative costs for each country.
Step-by-step explanation:
Living in poor developing nations is much cheaper than living in very rich developed nations, at least for the vast majority of the population. For example, a small house in Japan or Switzerland costs several hundreds of thousands of dollars, while a similar house in Pakistan or Paraguay will cost only a few teds of thousands of dollars.
The purchasing power parity tries to account for these differences in living expenses using the US dollar as the base currency, and in this case the Ghanaian oedi's value will be adjusted (receive higher value) to compensate for the lower cost of living in Ghana.
