I assume you mean "what sea is it located by" as Copenhagen is the capital city of Denmark:
Copenhagen is located by The Sound ("Øresund" in Danish) which is a strait between the Kattegat and the Baltic Sea
Copenhagen (located on the eastern coast of the Island Zealand) is facing a Strait called Øresund in Danish. The Øresund strait connected the Baltic sea to the South with Kattegat to the North.
No, Copenhagen is in Denmark, with the North Sea to the west and the Baltic Sea to the east.
