c. undesirable; zero
Here's why:
- Bertrand oligopoly is a market structure with a few firms selling identical products and competing solely on price.
- This intense price competition often leads to price wars, where firms keep dropping prices to undercut each other.
- In the end, firms may be forced to sell their products at a price very close to their marginal cost, which minimizes profits or even leads to losses.
Therefore, from a manager's standpoint, a Bertrand oligopoly is undesirable because it can result in zero or negative profits.
