Answer:
Option C, New York and Albany, is the right answer.
Step-by-step explanation:
New York has remained one of the most significant cities in the history of the United States. The main reason of its significance is the fact that during the larger part of the 1850's and in the early phase of the 1900's, thousands of settlers came in the U.S. and lived in New York City. Settlers or immigrants did not come from a particular country or land but came from various countries such as Ireland, Germany, Italy, Eastern Europe, and China. They began living in the Lower East Side of Manhattan due to the very fact that the rent in the tenements was very low.
On the other side, Albany was the city which had the least number of people during the 1850's.
