The power of manufacturers has been shifted to the hand of retailers thanks to ______.
A．the development of logistic technology
B．the development of marketing strategies
C．the labeling regulations
D．the bar code system

正确答案：D
解析：原文该句中的破折号表明使用条形码造成了权力从生产商到零售商的微妙转移，由此可见本题应选D“条形码”。选项C中的labeling一词在原文该段第2句提及，但这也是使用条形码造成的结果，而labeling和“权力转移”之间没有因果关系。
