Why did eBay sell its India operations to Flipkart?

After Flipkart announced the acquisition of eBay's India operations and raised $500 million from it, eBay's CEO Devin Wenig said, "Flipkart had a very strong close to last year". "There weren't going to be 10 winners, but maybe only one or two. And Flipkart, given all of that, was the natural party to align with", he added.
