Question

what is a cash - flow statement?
income that comes in at different amounts or at different times, or both
expense that remains the same from month to month
money received for work, as a gift, or through investments
a record that summarizes all of the income and outgo (spending) over a certain time period

Explanation:

A cash-flow statement tracks all cash inflows (income) and outflows (spending) over a defined period. The other options describe variable income, fixed expenses, and earned/unearned income respectively, which are components, not the statement itself.

Answer:

A record that summarizes all of the income and outgo (spending) over a certain time period
