Option C is the right answer.

Explanation:

Picher is a small town situated in Oklahoma. It is also called the ghost town because it became useless for any inhabitants to dwell in that area. It was titled to be a prohibited area for any inhabitants to live.

This town was recently hit by the F4 tornadoes which totally devastated the town and reduced the number of families residing in this area to twenty. It was a town that was a pathetic result of industrial abuse. Mining industry was booming in old days and the mine waste called chats were discarded on the land which created small hills.

This chat settled on everything as grime and polluted the area. People were unable to breathe and it created many physical and mental health issues.

When it rains, the fresh water gets mixed with this chat and becomes polluted. Due to water contamination, there was no fresh water supply in the area which forced the remaining residents to evacuate from that place.

its main object was the establishment of "settlement houses" in poor urban areas, in which volunteer middle-class "settlement workers" would live, hoping to share knowledge and culture with, and alleviate the poverty of, their low-income neighbors.
