A、Europe. B、Asia. C、South Korea. D、Japan. A题目问现在哪个地区是最大的手机赌博市场。新闻中提到，欧洲是手机赌博的最大市场，故A项正确。

Governments from Singapore to South Korea are increasingly lifting restrictions on gambling. But gamblers do not have to wait for new casinos to open to place their bets: They can just use their mobile phones. Walter Adamson, an Australian consultant for Internet and mobile services, says [1]the requirement for what is called mobile gambling is a phone that can connect to the Internet, where gaming operators offer special sites. "The provider of your system needs to provide a mobile Internet service and many telephone companies, particularly in Japan and Korea, provide Internet services on the mobile phone. Then they can access any Internet site that is designed for access by mobile phones." [2] Europe is the largest market for mobile gambling, but telecommunications analysts predict that Asia will catch up soon.
