选项：
A.10.87%.
B.11.36%.
C.13.61%.
解释：
B is correct.
The weighted average cost of capital is taking the sum product of each component of capital multiplied by the component’s after-tax cost.
First, estimate the cost of equity using the CAPM:
Cost of equity = Risk-free rate + [Equity Risk Premium × Beta]
Cost of equity = 3.0% + [5.5% × 2.00] = 14%
Now, calculate Bezak’s WACC:
题目说 asuuming interest on debt is tax-deductible 利息税可以扣除，在算WACC不是应该不算税吗？
