Respuesta :
The correct answer is option C, Candidates receive contributions from so many PACs that the effect of any single PAC is diluted.
Reason -
Different parties that contribute to a certain candidate assumes to at least have a recognition to their contribution but since there are several donors (big or small), usually the donors with small amount of donation get neglected and the effect of their contribution is felt diluted. This seems to generate a negative aspiration in the donor.
