Solution
Option 1 -> Interest Coverage Ratio measures a company's ability to pay interest on outstanding debt, not directly used for evaluating new investment opportunities.
Option 2 -> Cost of capital represents the minimum required return rate for investments and serves as the benchmark hurdle rate when assessing whether investment opportunities will create value.
Option 3 -> Dividend payout ratio indicates the proportion of earnings distributed to shareholders as dividends, not a primary metric for investment opportunity evaluation.
Option 4 -> Earnings per share measures profitability allocated to each share of stock, but is not the primary metric for assessing potential investment opportunities.
Hence, Option 2: Cost of capital -> When assessing investment opportunities, companies must compare expected returns against their cost of capital to ensure projects generate value above the cost of financing, making it the fundamental metric for investment decisions -> correct
