Bessarabia is a historical region that is now primarily part of which country?

Bessarabia is a historical region located in Eastern Europe, which has had a complex history marked by various territorial changes over the centuries. Today, the majority of Bessarabia is situated within the borders of Moldova. This area was part of the Principality of Moldavia before being annexed by the Russian Empire in the 19th century. Following World War I, Bessarabia united with Romania, only to be incorporated back into the Soviet Union after World War II. Eventually, when the Soviet Union dissolved, this region became part of the newly independent nation of Moldova.

The other countries listed—Luxembourg, Tonga, and Latvia—do not have historical or geographical ties to the Bessarabia region, making them incorrect choices. Therefore, recognizing that Moldova is the country that encompasses the majority of the historical region of Bessarabia is crucial for understanding its significance in the context of Eastern European geography and history.
