The answer is: A) Is defined as the 10 percent of U.S. households with the lowest incomes.

Explanation:

The poverty line (or poverty threshold) classifies people into poor or non-poor. If someone earns an income below that limit (poverty line) they are classified as poor. Usually this line or threshold is established as the smallest amount of money a person needs to live on.

So if a person is classified as poor, since they shouldn't be able to live solely on their income, they can request the assistance of government programs (e.g. Medicaid, food stamps).
