Based on the information provided, the conclusion that can best be drawn is A: Lithuania, Latvia, and Estonia share a common legal system.
This conclusion is supported by the fact that these three Baltic states have similar historical contexts (having been part of the Soviet Union) and have tended to align their legal frameworks, especially after gaining independence.
The other options are not accurate interpretations:
- B: Former communist countries have been left out of the European Union is incorrect as many former communist countries have successfully joined the EU.
- C: People and goods can move freely between Bulgaria and Ireland is not universally applicable, as EU regulations may allow for movement, but it does not imply all legal or logistical barriers have been eliminated.
- D: Portugal and Spain are no longer independent countries is false, as both maintain their sovereignty and independence.
Without seeing the actual map, this is the most plausible conclusion based on general knowledge about these nations.
