Letter A is correct. Many are the reasons that led to the United States expansion, but the desire to extend Christianity was not one of them. The U.S expanded westward across North America, initially as part of 'Manifest Destiny', but also as an outlet for their growing population. They also wanted an overseas empire like the other major western powers at the time (such as Britain and France). And, that included new markets and sources of revenue along with a more proeminent position on the world stage.

Where something is located :)
The immigration station on the west coast where Asian immigrants, mostly Chinese gained admission to the U.S. at San Francisco Bay. Between 1910 and 1940 50k Chinese immigrants entered through Angel Island. Questioning and conditions at Angel Island were much harsher than Ellis Island in New York.
I hope that helps.
