Explanation:

- Option 1: Obligation

- Correct Answer

- It refers to a duty or commitment. In legal terms, if you damage someone else's property, you have an obligation to compensate them for the repair costs.

-

- Option 2: Acknowledgement

- This means recognizing or admitting something. It doesn't fit here because merely acknowledging damage doesn’t mean you have to pay for repairs.

- Option 3: Requirement

- This implies something that is needed. While similar to obligation, it doesn’t have the same legal connotation. Obligations come from laws or contracts. Requirements are more general.

- Option 4: Appreciation

- This means recognition or enjoyment of the good qualities of someone or something. It’s unrelated to the context of paying for property damage.
