Consider the following scenarios for a company's costs of debt (rp) and equity (re) based on different debt-value ratios. Which capital-structure theory would explain these costs? a. b. M&M Proposition without tax? M&M Proposition with tax? Static trade-off theory? C. For each of these, choose the best one that applies and explain.
