Final answer:
In this scenario, specific performance can be obtained in options A and B as they both involve unique or specific items in the contract.
Step-by-step explanation:
In this scenario, the specific performance of a contract can be obtained in both options A and B. Option A states that the seller is contracted to sell Mike a farm, and if the seller wrongfully refuses to perform, Mike can seek specific performance. Option B states that Mike bought a unique hybrid bull, but the seller wrongfully failed to deliver it. In both cases, there are unique or specific items involved, which makes specific performance an appropriate remedy.
