单选题

　　【阅读理解】In 1994, United States Customs seized 204,391 pounds of cocaine，559,286 pounds of marijuana and 2,577 pounds of heroin. Just how much actually flows into the country is anyone’s guess. Some Customs officials estimate that only 10 percent of the drugs coming into the country are ever seized. In Miami, the District Attorney（检察长） won’t even prosecute small fry. “It’s got to be over five kilos of cocaine, above a kilo of heroin and more than 5,000 pounds of marijuana or it’s not something that we’re going to stop the presses on,” says Tom Cash, a retired agent. Which of the following could best replace the expression “small fry” in the paragraph?

　　 A、Small dogs

　　 B、Small sheep dogs

　　 C、Small smugglers（走私者）

　　 D、Small ringleaders（主谋）
