Which of the Following Statements Is CORRECT

Which of the following statements is CORRECT?

A) Other things held constant, the less debt a firm uses, the lower its return on total assets will be.
B) The advantage of the basic earning power ratio (BEP) over the return on total assets for judging a company's operating efficiency is that the BEP does not reflect the effects of debt and taxes.
C) The return on common equity (ROE) is generally regarded as being less significant, from a stockholder's viewpoint, than the return on total assets (ROA) .
D) The price/earnings (P/E) ratio tells us how much investors are willing to pay for a dollar of current earnings. In general, investors regard companies with higher P/E ratios as being more risky and/or less likely to enjoy higher future growth.
E) Suppose you are analyzing two firms in the same industry. Firm A has a profit margin of 10% versus a margin of 8% for Firm B. Firm A's debt ratio is 70% versus 20% for Firm B. Based only on these two facts, you cannot reach a conclusion as to which firm is better managed, because the difference in debt, not better management, could be the cause of Firm A's higher profit margin.
