Explanation:

- Contingent contract:

- These contracts rely on the occurrence or non-occurrence of an event.

- Contracts of indemnity are contingent since they depend on a loss being suffered.

- Your answer is right.

- Wagering contract:

- Based purely on chance, with mutual chances of gain or loss for parties.

- Different from indemnity, which protects against genuine potential loss.

- Quasi-contract:

- Not true contracts but imposed by law.

- Ensure fairness and prevent unjust enrichment without mutual consent.

- Void agreement:

- Not enforceable by law.

- Lacks essential elements of a valid contract, unlike a contract of indemnity which is enforceable.
