A university claims that its leadership training program is responsible for a 30% increase in graduates' management placements. Which logical flaw is most evident in this argument?
Correct: A
The flaw is a classic post hoc (correlation-causation) error. The program could be coincidental with external factors (market trends, economic shifts) affecting placement rates. Circular reasoning requires a self-referential premise, which is absent here. The other options don't apply to the argument structure.
