In the Early 2000s,some Entrepreneurs Took Advantage of a Reduction

In the early 2000s,some entrepreneurs took advantage of a reduction in the price of computed tomography (CT) scanning equipment by offering apparently healthy people preventive body scans to provide early detection of diseases.Which of the following is one reason for the failure of this effort to be profitable?

A) Negative publicity from "false positives" that occurred from the CT tests reduced the demand for this service.
B) The federal government halted the CT body scans until further tests proved the procedure was safe and effective.
C) The U.S.Congress passed a law that restricted the ability of the entrepreneurs to offer the body scans.As a result,the industry was not able to reach minimum efficient scale.
D) A lack of publicity resulted in few consumers being aware that the procedure was available.
