Development of more railroad systems contributed most to US westward expansion in the second half of the nineteenth century. Option B is correct.

Westward expansion, the 19th-century movement of settlers into the American West, started with the Louisiana Purchase and was driven by the Gold Rush, the Oregon Trail and a belief in "manifest destiny."

In 1862, Congress passed the Pacific Railroad Bill and numerous grants that allowed financial support for the Central Pacific and Union Pacific railroad companies. These two companies then constructed the transcontinental railroad.

here are some major conflicts i found. maybe pick one and do more research on it. (cause i ain't writing 6 paragraphs)

in 1877, the nez perce war took place.

1881 - president james garfield was assassinated.

1882 - the chinese exclusion act was passed.

1883 - a decision in the civil rights cases legalized racial segregation in the united states.

1887 - the dawes act was passed.

1893 - the panic of 1893 took place. (what a creative name)

and there are probably other topics you can find if you just search up "united states timeline," or "conflicts in the 19th century for america."

then once you find a topic you like find out how it affected the people of america and what not. (sorry if this feels a bit short changed, history was and never will be one of my strong topics)
