According to the Coase theorem, private parties can solve the problem of externalities if a. the number of parties involved is sufficiently large. b. the cost of bargaining is small. c. property rights aren't clearly defined. d. the initial distribution of legal rights favors the person being adversely affected by the externality.

b. the cost of bargaining is small.

Explanation:

The basic concepts behind the Coase Theorem is that conflicts can be solved regardless of the original rights and a solution that benefits all parties can be found as long as transaction costs (bargaining costs) are low or nonexistent, and the output of the negotiation process efficiently allocates resources. This theorem is useful when you are trying to find solutions to negative externalities.
