版主能否给个定论

In one state, all cities and most towns have antismoking ordinances.  A petition entitled “Petition for Statewide Smoking Restriction” is being circulated to voters by campaign workers who ask only, “Do you want to sign a petition for statewide smoking restriction?”  The petition advocates a state law banning smoking in most retail establishments and in government offices that are open to the public.

Which of the following circumstances would make the petition as circulated misleading to voters who understand the proposal as extending the local ordinances statewide?

A Health costs associated with smoking cause health insurance premiums to rise for everyone and so affect nonsmokers.
B In rural areas of the state, there are relatively few retail establishments and government offices that are open to the public.
C The state law would supersede the local antismoking ordinances, which contain stronger bans than the state law does.
D There is considerable sentiment among voters in most areas of the state for restriction of smoking.
E The state law would not affect existing local ordinances banning smoking in places where the fire authorities have determined that smoking would constitute a fire hazard

我个人倾向B，但是NN们对C的解释也使我很困扰，这道题有定论吗，请版主回答下，谢过

这题是要找下列何种情况会造成misleading to voters

注意文章中Statewide Smoking Restriction与
        a state law banning smoking这两个范围有差别就可判断出ans

Ans:C 就指出了会misleading to voters 的情况

请指教

觉得C有道理，但是我看的角度和你不一样，to voters who understand the proposal as extending the local ordinances statewide?我想是被调查的人认为会使地方法律扩展到州，但是，C项说的是州法律取代地方法律，而且更弱比州法律，这就是误导，还有人有别的看法吗？请指教
