Explanation:

- Transient poor (Option 2): These individuals or households move in and out of poverty over time. They are not consistently poor but experience periods where they fall below the poverty line.

Correct Answer

- Churning poor (Option 3): Similar to transient poor, churning poor also move in and out of poverty. They are not always the same individuals but fluctuate in economic status.

- Occasionally poor: This term is not generally used as a specific category in poverty studies; it's more a description, like those experiencing brief periods of poverty.

- Always poor (Option 4): These individuals are persistently below the poverty line and have minimal changes in economic status.
