Answer:
The correct answer is: The Treaty of Lisbon.
Explanation:
The Treaty of Lisbon amends the two treaties (the Treaty of Rome and the Treaty of Maastrict), signed in 2007, and became effective in 2009. It was signed with the aim of resolving the issue of further institutional functioning of the European Union. The Treaty of Lisbon complements the existing treaties on the European Union and the European Community, without replacing them.
