Explanation:

- An executory contract is one where terms are set but the obligations are yet to be fulfilled, such as an agreement to sell goods at a future date.

- Correct Answer: Option 1 - Executory Contract

- An executed contract is one where all parties involved have fulfilled their contractual obligations. This wouldn’t fit an agreement to sell, as the sale has not yet been completed.

- An implied contract is one where the terms are not explicitly stated but understood through actions or circumstances. An agreement to sell typically has explicit terms.

- An expressed contract is one where terms are clearly stated either verbally or in writing. An agreement to sell is usually expressed, but it is also executory until fulfilled.
