Answer:
The correct answer is D. The two states that border Washington DC are Maryland and Virginia.
Step-by-step explanation:
Washington DC is the capital of the United States. It is administered as a federal district, an entity different from the fifty states that make up the nation, and reports directly to the federal government. The District of Columbia was founded on July 16, 1790, and in 1791 a new city called Washington, east of the existing Georgetown, was formalized within the district. In 1871 the governments of these two cities and the rest of the towns of the district were unified into a single entity, D.C.
It is located on the banks of the Potomac River and is surrounded by the states of Virginia to the west, and Maryland to the north, east and south.
