Answer:
The correct answer is D) Northeast
Step-by-step explanation:
The NorthEastern region of modern United States was one of the first places to be colonized by the British. Some of the oldest cities from the colonial period are found in this area.
Hence, this area has always been the most highly populated region in the country and was the first to industrialize. By the time of the Civil War, the southern States were mostly based on agriculture and had a very different culture than the north-east which had large urban centers.
The northeast is home to the largest city in the United States, New York, the current capital of Washington D.C and also the country's first temporary capital city, Pennsylvania.
