Would be interesting to see the official answer for this problem -
Here is my take ; IMO-option C
Stem-American voting system should be discarded, because pre election polls did not translate into positive results for the candidates leading the polls..
So negate the choice , if it weakens the agrument then it is ur ans .!

b) so if voting DID significantly alter its feelings towards a candidate then this proves that the system is unjust and is a support for the argument .
C) If the candidate winning the election DID not consistently spend more money than the candidate leading the pre election polls it shows that the system is just and there is no need for change ;
hence this is my ans !
