Final answer:
The answer is option C. The transcontinental railroad did NOT make the transport of coal from Alaska more accessible.
Step-by-step explanation:
The correct answer is c. It made the transport of coal from Alaska more accessible.
The transcontinental railroad, completed in 1869, connected the eastern states with the western states, providing a faster and more efficient mode of transportation. It played a significant role in the expansion of the United States, facilitating trade and the movement of people. However, it did not make the transport of coal from Alaska more accessible.
Instead, the transcontinental railroad primarily focused on connecting the Union states across the country, making shipping cheaper and more efficient, and allowing people to move across the country more quickly.
