The correct answer is A) The new regulations caused investors to lose money on their stocks.
The statement that was NOT a reason for the failures of the Interstate Commerce Act, the Sherman Anti-Trust Act, and the Dingley Act of 1897 is "The new regulations caused investors to lose money on their stocks.
The Interstate Commerce Act of 1887 was passed to regulate the industry of railroads in the US.
The Sherman Anti-Trust Act of 1890 was passed to regulate competition and prohibit the formation of monopolies of the US such as the oil monopoly created by the Standard il company of John D. Rockefeller. The Dingley Act of 1897 was passed to reverse the lowering of rates resulted from the Revenue Act of 1894.
So, the reasons for the failure of those acts were that Americans had no means of making imported goods more inexpensively, big corporations created ways to appear to comply with the regulations when they really did not, and wealthy companies used money and power to get around the new regulations.
