Which province in Canada is connected to the eastern provinces by the Transcontinental Railroad?

The correct choice identifies British Columbia as the province connected to the eastern provinces by the Transcontinental Railroad, specifically through the Canadian Pacific Railway. This railroad was a significant engineering achievement that facilitated travel and trade across the vast expanse of Canada, linking the western provinces to the east. The completion of the railway in 1885 was instrumental in uniting the country physically and economically, allowing for the movement of people and goods between diverse regions, including British Columbia in the west and provinces like Nova Scotia and others in the east.

While other choices represent important provinces within Canada, they do not specifically highlight the connection established by the Transcontinental Railroad between the east and west. Alberta and Ontario are central provinces, while Nova Scotia is positioned in the eastern part of the country, but it is British Columbia that plays a key role as the western terminus of this vital transportation link.
