Since City X passed

    Since City X passed a regulation requiring fast food restaurants to post the caloric content of their food in prominent places, total revenue at the city’s fast food restaurants has decreased 10 percent. Clearly, City X’s regulation has encouraged people to eat healthier food.

    Which of the following, if true, casts the most doubt on the conclusion drawn above?

    A) The average price of meal at a fast food restaurant in City X has decreased by 5 percent.

    B) City X passed the regulation in response to a nation wide obesity epidemic.

    C) After the regulations were passed, a number of City X’s fast food restaurants closed down and moved their operations to locations outside the city.

    D) The population of City X has remained unchanged since the passing of the regulation.

    E) Surveys show that many citizens of City X do not approve of the new regulations.

    C is the OA.

    This type of questions are hard to me. Experts, can you solve it and explain it to me?
