能解释下B和C是怎么互相影响的吗

问题如下：

Compared to the pension assumptions Terra Mercado used in 20X2, which of the following pairs of assumptions used in 20X3 is mostlikely internally inconsistent?

选项：

Estimated future salary increases, inflation

Discount rate, estimated future salary increases

Expected long-term rate of return on plan assets, discount rate

解释：

A is correct. The company’s inflation estimate rose from 20X2 to 20X3. However,

it lowered its estimate of future salary increases. Normally, salary increases are

positively related to inflation.
