D

The firm's Weighted Average Cost of Capital (WACC) is a weighted average of the component cost of capital. In this case 10%(borrowing rate) x (1-.4)Tax savings

= 6% is the component cost of debt. $5 (preferred dividend) / 49(Par minus floatation cost) = 10.2% is the component cost of preferred stock. Thus the WACC =

.45(6%) + .5(15%) + .05(10.2%) = 10.71%
