The correct answer is B (8x).

Explanation:

• The interest coverage ratio using EBIT (Earnings Before Interest and Taxes) is calculated as: $\text{Interest Coverage Ratio} = \frac{\text{EBIT}}{\text{Interest Expense}}$
• Here, EBIT is equivalent to the operating income, which is $120 million.
• Therefore, the calculation is: $\frac{120}{15} = 8$

Why not A or C?

• Option A (7x) incorrectly uses net income plus depreciation and amortization, which is not the correct measure for EBIT.
• Option C (9x) incorrectly includes depreciation and amortization in the numerator, resulting in EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization), not EBIT.
