b. nevada
c. california
d. new mexico

The answer is letter A. 

In 1869, six years after the work on the Union Pacific Railroad began, workers of Central Pacific Railroad from the west and the Union Pacific Railroad from the east met at the Promontory Summit of the state of Utah. This was the place where Governor Stanford drove the Golden Spike as a symbolism for the completion of the transcontinental railroad.

At present, this railroad is responsible for hauling freights and is operated by 8,500 locomotives that run over 32,000 miles in 23 states west of Chicago, Illinois, New Orleans, and Louisiana. It is currently the largest railroad network in the United States serviced by more than 47,000 employees.
