Answer:
D. Cost of debt (rd)
Since more debt is taken, the interests payments or cost of debt should increase.
E. Cost of equity (rs)
More leverage = higher risk, and higher risk = higher cost of equity.
Explanation:
Return on assets will probably decrease, because the assets should remain the same but net income should decrease.
Net income will probably decrease because the company will now pay more interests due to higher debt.
Basic earning power should remain unaffected, because EBIT and assets should not change.
