选项：

B.unexpectation of future inflation rate.
C.expectation and unexpectation of future inflation rate.
解释：
C is correct.
考点：Break-even inflation rates
解析：BEI的定义。其中Break-even inflation rates=expect future inflation+uncertainty of future inflation
课上不是说短期债只需补偿expected inflation rate，长期债才要在expected inflation rate基础上补偿unexpected inflation rate吗？
