Answer:
A) Country 1's PPF lies further to the right than country 2's PPF.
Step-by-step explanation:
Production Possibility Curve shows the combination of two goods, that an economy can produce - by utilising given resources & technology best efficiently.
If country 1 produces twice the output of both goods compared to country 2. Then, country 1's PPF would lie further to the right than country 2's PPF. As, more quantities implies rightward shifted PPC, signifying more quantities of goods that can be produced.
Efficient or inefficient production leads to production inside or on PPC, doesn't shift PPC. Population change is also irrelevant in this case.
