Concept:
Purchasing Power Parity (PPP) is an exchange rate that equalises the purchasing power of different currencies by considering the prices of a common basket of goods and services.
Unlike nominal Per Capita Income, PPP adjusts for differences in price levels across countries, making international comparisons of living standards more meaningful.
Step 1: Understand Purchasing Power Parity (PPP).
PPP reflects the amount of goods and services that can actually be purchased with a given income in different countries.
Thus,
\[
\boxed{
\text{PPP adjusts income using differences in purchasing power.}
}
\]
Step 2: Examine the given options.
• [(A)] Health and education are components of the Human Development Index (HDI), not PPP.
• [(B)] PPP adjusts for differences in purchasing power and exchange rates, making international comparisons more realistic.
• [(C)] PPP and Per Capita Income are different concepts.
• [(D)] PPP does not directly measure income distribution.
Hence,
\[
\boxed{
\text{PPP provides a better comparison because it adjusts for purchasing power differences.}
}
\]
Therefore,
\[
\boxed{(B)}
\]
