The correct options are:
C. balance sheet; cash flow statement
A balance sheet shows the value of assets, liabilities, and equity at a single point in time.
A cash flow statement shows the income, expenses, and cash flow over a specific time period.
The other options are incorrect:
A. cash flow statement; income statement - An income statement shows profitability over a time period, not asset/liability values at a point in time.
B. balance sheet; income statement - See explanation for A.
D. cash flow statement; income statement - See explanation for A. An income statement shows different information than a cash flow statement.
So in summary, the balance sheet and cash flow statement together provide a more complete picture of a company's finances and profitability.
