D). The urban underclass consists of mostly recent immigrants.
The reason why answer choice "D). The urban underclass consists of mostly recent immigrants" would be the correct answer because this is something that's not a reason the urban underclass differs from the lower class.
The urban underclass is a group of people who stands out in a society because their lack personal skills, wealth, income, property, and etc.
The urban underclass could be anyone, meaning that anyone could be part of the urban underclass if they're were in that class.
The urban underclass doesn't only consist of recent immigrants, that would be a false statement. The urban underclass could be people who were born in the country, or people that were immigrants but immigrated along time ago, that's where the "anyone can be in it" comes from. It's not only filled with recent immigrants, there could be citizens that are part of the urban underclass.
