Explanation: The Production Possibility Curve (PPC) is a fundamental concept in economics that illustrates the trade-offs between two goods that an economy can produce given its resources and technology. The PPC is typically drawn as a concave curve, bowed outward from the origin, reflecting the principle of increasing opportunity cost.
The slope of the PPC represents the opportunity cost of producing one good over the other. Opportunity cost is the value of the next best alternative that must be forgone. In the context of the PPC, it is the amount of one good that must be given up to produce one more unit of the other good.
As we move along the PPC from left to right, the opportunity cost increases. This is because resources are not equally efficient in producing both goods. Initially, the economy may have resources that are highly efficient in producing one good, but as more of that good is produced, the economy must use resources that are less efficient in producing it. Consequently, the opportunity cost of producing additional units of that good increases.
For example, consider an economy that produces only two goods: wheat and cotton. Initially, the economy may have land and labor that are highly suitable for growing wheat. As more wheat is produced, the economy must use land and labor that are less suitable for wheat and more suitable for cotton. This means that to produce one more unit of wheat, the economy must give up more units of cotton than before, increasing the opportunity cost.
Therefore, as we move from one point to another on the PPC towards the right, the slope increases, reflecting the increasing opportunity cost. This is why the correct answer is (A) Increases.
Understanding the PPC and its slope is crucial for comprehending the trade-offs and opportunity costs in resource allocation, which is a key concept in Indian General Knowledge, particularly in economic contexts.
