Industrialists from the cuntry Distopia were accused of promoting the Distopian intervention in the Arcadian civil war merely to insure that the industralists' facilities in Aradia made substantial profits during the war.

Which of the following, if true exposes a serious flaw in the argument made in the second sentence above?

B The largest proportion of Distopia's federal expenses is borne by those who receive no significant industrial profits.

c Most Distopian industrialists' facilities in Arcadia are expected to maintain the level of profits they achieved during the war.
