Which landlocked country shares a border with Ukraine?

Moldova is the correct answer because it is a landlocked country located in Eastern Europe, bordered to the north, west, and south by Ukraine. Its geographical position places it directly adjacent to Ukraine, making it one of the few landlocked countries that share this type of border.

The other options do not fit the criteria. Austria, while being a landlocked country in Central Europe, does not share a border with Ukraine; instead, it is bordered by several other countries to the west and south. Italy and Slovenia are both located in Southern Europe and share borders with countries further from Ukraine, such as Slovenia with Italy and Austria rather than directly to Ukraine. Therefore, Moldova is unique among the options provided as the only landlocked country sharing a border with Ukraine.
