The correct answer is D) The steady salaries offered to mine laborers enticed many to seek jobs in mining towns.
The statement that most accurately describes how economic incentives led to the development of boom towns in the American West is "The steady salaries offered to mine laborers enticed many to seek jobs in mining towns."
The natural resources in the West attracted many people who saw a future in the exploitation of minerals and other raw materials. For instance, workers in the mines received a steady salary and this attracted many more people to work in the mines. Gold was the reason. If someone discovered a gold deposit, many people went to that area and established a camp to start the mining works. With them, it also arrived people that traded food, clothes and offered other services so they formed towns or Boomtowns that disappeared at the moment when there were no more gold. Then those places became Ghost towns.
