Answer:
b. Possibility that loans in some countries may not be repaid because of political upheaval.
Step-by-step explanation:
This is what is included in the country risk in the risk premium in interest rates. The risk premium refers to a return on investment that a person expects an investment will yield. If a country experiences political upheaval, then there is a good chance that the loans of the country will not be repaid due to the conflict. This is referred to as "country risk."
