The correct answer is **cheating by firms**.

In an oligopoly, firms may attempt to collude to set prices or output levels to maximize their collective profits. However, cheating—where one or more firms do not adhere to the agreed-upon prices or output levels—can undermine collusion. If firms cheat, it can lead to price wars and diminished profits for all firms involved, making it a significant obstacle to successful collusion.

The other options, such as prosperous economic conditions, a small number of firms, and a homogenous product, can potentially facilitate collusion rather than hinder it.
