Explanation:

- Poverty line: This is the correct term. It refers to a designated point in income distribution that classifies individuals as either poor or non-poor. It helps in identifying the population needing economic assistance.

- Poverty cut-off: This phrase is sometimes used interchangeably with "poverty line," but it's not the standard term. It emphasizes the point that divides poverty from non-poverty.

- Poverty: This is a broad term describing the state of having insufficient financial resources to meet basic living costs.

- Poverty distribution: This describes how poverty is spread across a region or population group and does not specifically refer to the cut-off point.
