The correct answer is option 1, Belarus. The Baltic States are a group of three countries located in Northern Europe, on the eastern coast of the Baltic Sea. They are Estonia, Latvia, and Lithuania. These countries share similar cultural, historical, and geopolitical characteristics. However, Belarus is not considered a Baltic State. It is located to the east of the three Baltic States, between Poland and Russia. Belarus, also known as the Republic of Belarus, is a landlocked country and does not have direct access to the Baltic Sea. Therefore, it is not considered one of the Baltic States. It is important to note the distinction between the Baltic States and neighboring countries to have a better understanding of the geography and political divisions of the region.
