Explanation

Bulgaria and Romania officially became member states of the European Union on January 1, 2007. This expansion was part of the fifth enlargement process, often referred to as the second part of the fifth enlargement following the 2004 addition of ten other countries. The other countries mentioned in the options joined at different times: Belgium was a founding member in 1957, Slovenia and Hungary joined in 2004, and Croatia became a member much later in 2013. Therefore, Bulgaria and Romania is the only pair that fits the 2007 timeline.
