Which of the following countries does NOT share boundary with Ukraine?

Ukraine is a country in Eastern Europe that shares land boundaries with seven sovereign states. According to official geographical data, these bordering countries are Belarus, Hungary, Moldova, Poland, Romania, Russia, and Slovakia [1]. Specifically, Ukraine shares a 613.8 km border with Romania to the south and southwest [1], a 1,222 km border with Moldova to the southwest, and a 535 km border with Poland to the west. While Lithuania was a fellow constituent republic of the Soviet Union alongside Ukraine [2], it does not share a direct land boundary with Ukraine. Lithuania is located further north and shares borders with Poland, Latvia, Belarus, and the Russian exclave of Kaliningrad. Therefore, Lithuania is the country among the options that does not share a boundary with Ukraine.
