Government can lawfully prevent a political rally from taking place
a. under no circumstances; people have an unconditional right to express their views.
b. when the rally would require unduly expensive police protection.
c. when the views of those holding the rally are unpopular.
d. when it can demonstrate that harmful acts will necessarily result from the rally.
e. None of these answers is correct.
d is true, but it is virtually impossible to demonstrate...will necessarily... Even the with the KKK and those right wing "patriot" organizations are protected. A good example 20 years ago was the protests at the front door of abortion clinics, even when the protesters had posted death notices with pictures and addresses of the doctors. It is very difficult to demonstrate that something will result.
I would go with e.
