The state of California recently adopted legislation that requires bars and restaurants to ban smoking inside their establishments unless the restaurants have a separate room with separate heating, ventilation, and air-conditioning (HVAC) systems that can be designated as a smoking room. Sports bars that do not already have rooms with separate HVAC systems need to construct them in order to accommodate patrons who wish to smoke, or the lack of a smoking room will cause these bars to go out of business.

Which of the following, if true, would most strengthen the argument above?

A. Smoking patrons care enough about being able to smoke in a sports bar that they would leave bars without smoking rooms in favor of those with smoking rooms in large enough numbers to drive the bars without smoking rooms out of business.
B. Employees of sports bars without smoking rooms are known to smoke outside during breaks, and patrons are welcome to do the same without breaking the law.
C. Most patrons of the average sports bar do not smoke anyway and will shy away from bars that do have smoking rooms.
D. The new smoking legislation should provide equal protection from any hazards associated with smoking to all patrons of restaurants and bars.
E. To construct a new smoking room, bars will need all the proper construction licenses, a certified contractor, and a plan from an architect. Construction will take at least three months for the average bar.
