问问D。。

问题如下：

Rating agencies typically assign two types of ratings to debt-issuing countries: local currency debt ratings and foreign currency debt ratings. Historically, foreign currency debt has had a higher default rate than local currency debt. What are the main reasons for this difference?

选项：

This is a statistical deviation because the debt body is one and the default rate for local and foreign currency debt should be the same.

Debt denominated in a foreign currency usually has less collateral than debt denominated in a local currency.

Debt denominated in local currency can be repaid through monetary expansion.

Governments in distress tend, for political reasons, to consider defaulting on foreign currency debts first.

解释：

C is correct.

解析：

因为本币债务可以通过发行货币来偿还，但外币债务无法以这一方式来偿还，所以本币债务的信用风险小于外币。
