From which region did Zebra/Quagga Mussels originate?

Explanation:
Zebra mussels and the closely related quagga mussel originate from the freshwater systems around the Black Sea, specifically the southern Russia region (the area including the lakes and rivers of that part of Europe). This is their native range, where they evolved before being moved elsewhere by human activities. They later spread to other parts of the world, such as North America and Western Europe, primarily through ballast water from ships. So the correct region identifies where these mussels first evolved and lived before becoming invasive elsewhere.
