Sentence B. My mother "emigrated" from China and came to the United States uses the underlined word correctly. <u>Emigrate</u> means to leave one country to settle in another, and it implies a permanent move. On the other hand, <u>immigrate</u> is to enter and settle in a foreign country. The difference between these two words is that emigrate is the act of leaving a country and immigrate the act of entering a country.
