Explanation:

- Unascertained goods refer to goods that are not specifically identified at the time the contract is made. They are simply part of a larger bulk or class.

- Option 1: Specific goods – These are goods that are clearly identified and agreed upon at the time a sales contract is made.

- Option 2: Generic goods ( Correct Answer) – Unascertained goods are also known as generic goods because they are defined by type or category, not by individual identification.

- Option 3: Future goods – These are goods to be manufactured or acquired by the seller after the contract is made.

- Option 4: None of the above – This is not correct, as “generic goods” matches the definition.
