Final answer:
The correct answer is B. Turkish banks, partly owned by those in the Eurozone, are at risk if the Eurozone banks struggle financially. Turkey's practice of borrowing in foreign currencies and historical defaults creates heightened risks for its banking sector. The assertion is probably true.
Step-by-step explanation:
Given Turkey's economic situation where banks borrow money in a widely used currency like the U.S. dollar or Euro, and then convert these to the Turkish lira, there are significant risks if the value of the lira depreciates. Extreme budget deficits mean that aggregate demand may lead to high inflation, and the fear of not repaying debts may deter international investors. Turkey's history of defaulting on loans, such as the six times in the last 175 years, raises concerns for foreign investors about the return on their investments. Should the European banks face financial difficulties, Turkish banks partially owned by these Eurozone banks could indeed suffer due to their dependency on foreign capital.
The claim that Turkish banks may face instability if European partner banks encounter financial trouble is Probably True, as any depreciation in the Turkish lira would make it hard for these banks to repay international loans denominated in stronger currencies.
