Answer: Reformation
Step-by-step explanation: Removal or alteration by court order of the current contract at the request of one of the parties to the agreement is called reformation.
Reformation will be required when there is evidence that the participants have not meant the expression as written or an accident or confusion has caused an omission.
Thus, from the above we can conclude that the correct option is D as the resource mineral is not able to perform under the conditions specified in the contract.
