Answer:
The correct answer is C. buying up small railroad companies to drive up his business
Step-by-step explanation:
According to history, Jay Gould between 1836-1892 of his lifetime was a railroad mogul in the United States predominantly in New York City. He was also a financier. Jay Gould's interest in the railroad industry grew beyond measures as he started with a move to invest in small railroads after much deliberation in 1859. He was involved in so many railroad projects that led him into holding high positions in the industry and by 1867, he was made director of "Erie Railroad".
To grow his business and fully own the railroad industry, Jay Gould started some fraudulent dealings in his stocks and paying bribes to some bodies in government. He properly invested in "Union Pacific Railroad" stocks and soon gained maximum control.
