Opponents complain that the taxi and room-rental businesses ______.

A.frequently make anti-competitive market behavior

B.are often involved in illegal business practices

C.are lacking in necessary rules and regulations

D.have caused a lot of accidents and crimes

参考答案：C

参考解析：

推理判断题。根据第三段前两句“The newcomers’ opponents, … complain that the likes of Airbnb and Lyft dodge (躲避) the rules and taxes that apply to conventional businesses. Regulations exist to keep hotel rooms clean and fire alarms in working order, … their knowledge of the streets”可知，反对者的理由是，共享经济中的出租车和客房租赁业务缺乏必要的规章制度。主要体现在：传统的出租车行业要求投保，查看司机的犯罪记录和测试他们的交通知识，而现在的uber司机则不用；传统的酒店要求保持客房干净，火警正常工作，而共享经济的Airbnb客房则没有这些约束，因此C项正确。故选C。
