Which insurer would be classified as a foreign insurer in Washington, D.C.?

To determine which insurer is classified as a foreign insurer in Washington, D.C., it's important to understand the distinction between domestic, foreign, and alien insurers. A domestic insurer is one that is incorporated in the state or territory in which it operates. A foreign insurer is one that is incorporated in a different state or territory from where it is operating.

In this case, Washington, D.C. is treated as a separate jurisdiction. Therefore, an insurer incorporated in Delaware, Virginia, or Maryland would be classified as a foreign insurer in Washington, D.C., with a particular note on the examples given.

The choice indicating an insurer incorporated in Maryland is the best fit for the answer because Maryland is indeed a neighboring jurisdiction of Washington, D.C., and it meets the criteria for being classified as foreign. In contrast, an insurer incorporated within Washington, D.C. would be considered domestic, as it operates within its originating jurisdiction.

Thus, the correct answer showcases the definition of foreign insurers and illustrates how the operational boundaries of insurance jurisdictions work.
