B. A debt is the total of accumulated and unpaid deficits is the relationship between a debt and a deficit.
The relationship between a debt and a deficit is that a debt is essentially the accumulation of deficits over time.
A deficit occurs when expenditures exceed revenues in a given period, usually a fiscal year.
If a government or entity consistently runs deficits, the total amount of those deficits adds up to the overall debt. In other words, the deficit is an annual shortfall, and the debt is the cumulative result of these annual deficits.
Therefore, B. A debt is the total of accumulated and unpaid deficits is the relationship between a debt and a deficit.
