I have to get full marks on this math. Requesting to do this math carefully. Thanks in Advance

WACC-Book weights and market weights Webster Company has compiled the information shown in the following table: a. Calculate the weighted average cost of capital using book value weights. b. Calculate the weighted average cost of capital using market value weights. c. Compare the answers obtained in parts a and b. Explain the differences. a. The firm's weighted average cost of capital using book value weights is %. (Round to two decimal places.) b. The firm's weighted average cost of capital using market value weights is %. (Round to two decimal places.) c. Compare the answers obtained in parts a and b. Explain the differences. (Select the best answer below.) A. The market value approach yields a higher cost of capital because the costs of the components of the capital structure are calculated using the prevailing market prices. Since the common stock is selling at a higher value than its book value, the cost of capital is much higher when using the market value weights. B. The book value approach yields a lower cost of capital because the costs of the components of the capital structure are calculated using the prevailing market prices. Since the common stock is selling at a higher value than its market value, the cost of capital is much higher when using the book value weights. C. The book value approach yields a higher cost of capital because the costs of the components of the capital structure are calculated using the prevailing market prices. Since the common stock is selling at a lower value than its market value, the cost of capital is much higher when using the book value weights. D. The market value approach yields a lower cost of capital because the costs of the components of the capital structure are calculated using the prevailing market prices. Since the common stock is selling at a lower value than its book value, the cost of capital is much lower when using the market value weights.
