Suppose that Billy McGee owns the Internet domain www.ironmaiden.com. Iron Maiden, the legendary British heavy metal band, was given the rights to the name by the World Intellectual Property Organization. Iron Maiden values the domain name at $250,000 and Billy McGee values the domain name at $330,000. The Coase theorem suggests that:
(a) Iron Maiden will buy the domain name from Billy McGee for less than $330,000.(b) Billy McGee will pay Iron Maiden between $250,000 and $330,000 to keep the domain name.(c) Billy McGee will pay Iron Maiden more than $330,000 to keep the domain name.(d) Iron Maiden will take the domain name.

Coase theorem states that in a situation of conflicting property right . the trading parties should be able to arrive at a mutually benefiting term that should cover the the cost and other underlying value of the property involved.

In the scenario above , for Billy McGee to retain the domain name as the WIPO has already given the right to Iron maiden , he will have to pay iron maiden more than the value to iron maiden and less than the value to him so that the two can mutually benefit from the transaction
