Why Is Weber More Acceptable Than Marx to Certain Schools

Why is Weber more acceptable than Marx to certain schools of sociology, especially in the United States?

A) Weber appeals to sensibilities conditioned by a society that is generally antiradical and believes that individuals are not shaped by economics.
B) Weber's vagueness allows American sociologists to fit him to their agenda.
C) Marx had omitted the importance of bureaucracies in the modern era such that Weber is a necessary and profound course correction.
D) Weber is the more authentic because he saw that the proletariat, as a class, would need a political party to act on its behalf, that is, an intelligentsia (e.g. the Bolsheviks) .
