Which is the most accurate statement?

A) Although no one theory can explain all poverty in the U.S. ,welfare dependency probably explains most of it.
B) Poverty can be explained mainly by the laziness of the poor.
C) There is no theory of poverty that really explains much.
D) There are many theories of poverty,and while none can explain all poverty,each does explain some of it.

Option D acknowledges that there are multiple theories of poverty, and while none can fully explain all poverty, each theory has some merit in explaining certain aspects. This statement is the most accurate as it recognizes the complexity of poverty and the need for multiple approaches to addressing it. Options A and B are incorrect as they oversimplify the causes of poverty and place blame solely on the poor. Option C is also incorrect as it implies that there is no useful framework for understanding poverty.
