选项：

The estimation of the value of human capital, the future income, is discounted at the:

A.

real risk-free rate

B.

nominal risk-free rate plus a premium for inflation

C.

nominal risk-free rate plus a premium associated with occupational income volatility

解释：

C is correct. A premium associated with the occupational income is added to the nominal interest rate. The numerator in the human capital valuation is the anticipated income. A is incorrect because the income that is being discounted is in nominal terms. B is incorrect because the nominal risk-free rate includes an inflation premium.
