Answer:
The logical form of this argument is b. Disjunctive Syllogism.
Step-by-step explanation:
The argument presents two mutually exclusive options: either there is a massive, multi-million dollar conspiracy at work, or the electorate has decided that Senator Wiggins is the best candidate for the position. It then asserts that the electorate has decided that Senator Wiggins is the best candidate, which eliminates the second option. Therefore, the conclusion is that there is not a massive, multi-million dollar conspiracy at work, which follows from the elimination of the second option. This pattern of reasoning is known as a disjunctive syllogism.
