Falling opportunity cost between two goods
Rising opportunity cost between two goods
Constant opportunity cost between two goods
None of the above
✅ The correct answer is B.
The shape of PPC is concave due to rising opportunity cost between two goods. Most of the PPF curves are concave due to the inadaptability of the resources. The law of increasing opportunity cost states: as the production of one good rises, the opportunity cost of producing that good increases.
