Answer:
If the several companies in the tobacco industry produce similar products but have very different marginal costs: they are more likely to engage in tacit collusion than firms with similar costs.
Step-by-step explanation:
Tacit collusion occurs when firms silently agree on a strategy that will benefit them both either by cutting cost or increasing patronage.
If the several companies in the tobacco industry produce similar products but have very different marginal costs, some firms might decide to collude tacitly by lowering their prices therefore controlling a larger potion of the addressable market.
The reason this action is taken silently is because express collusion will attract legal sanctions that will be supported by firms within the industry that did not collude.
