Answer:
C) No, but she has a potential claim for the cost of the climbing equipment.
Explanation:
When regulations affect the performance of a contract, the contract can be dismissed since it becomes unenforceable without any party involved being accountable for any type of breach.
Romanita will not be able to claim the $500 payment because the contract is unenforceable, but she can claim that the offeror pays her the $150 she spent in equipment. She will probably have to give the equipment to the offeror.
