Explanation:

- Specific Performance (Option 4):

- Correct Answer

- When a rare article or unique item with no market substitute is involved, courts often order the contract to be fulfilled as agreed, known as specific performance.

- Quantum Meruit (Option 1):

- This is when payment is due for services provided, even if a contract was not fully executed. It's not usually for tangible, rare items.

- Rescission (Option 2):

- This cancels the contract, allowing parties to walk away as if it never existed. It's more common in cases of misrepresentation or mistake.

- Injunction (Option 3):

- This prevents a party from doing something, rather than ordering them to do something specific, like delivering a rare item.
