Answer:
C. Mining towns did well with little regulation from the government, leading to the establishment of more independent towns in the West.
Step-by-step explanation:
During the 1800s there was a mining fever in the US and particularly for mining gold. For the mines to have workers new towns needed to be build so that people could live there and work there. Many towns like this got abandoned and turned into ghost towns after the mines would deplete but the towns that had a better environment thrived since many workers found a better quality of life there.
