Final answer:
The term 'underclass' in the Weberian model describes those in the US class structure who face long-term deprivation, often having scarce employment, low education and income levels, and high unemployment rates. The correct option is B.
Step-by-step explanation:
In the Weberian model of the U.S. class structure, the term 'underclass' refers to those who are poor, seldom employed, and caught in long-term deprivation that results from low levels of education and income and high rates of unemployment. The underclass is considered the United States' lowest tier, often living in inner cities and experiencing unemployment or underemployment.
They may perform menial tasks for little pay, and some are homeless, relying on welfare systems which may not adequately cover their basic needs. This situation contrasts with the working poor, who have unskilled, low-paying employment without benefits, and the working class, who perform routine tasks under close supervision.
