Final answer:
Denmark is the southernmost Scandinavian country located on the Jutland Peninsula and is bordered by the Baltic Sea to the east.
Step-by-step explanation:
The southernmost Scandinavian country on the Jutland Peninsula, surrounded by the Baltic Sea to the east, is Denmark. Denmark is known for its rich Viking history, having been a part of the North Atlantic exploration and expansion. The capital city of Denmark, Copenhagen, is also a major port city. This country, along with its neighbors Sweden and Norway, has a relatively low population density compared to its size, mirroring the historical expeditions of the Danes who used to explore the British Isles, among other destinations.
