The provision described is a 'Force Majeure' clause. This clause excuses parties from performing their contractual obligations due to unforeseeable events beyond their control. Among the choices provided, an 'Exclusion clause' is the most appropriate answer. A Force Majeure clause functions as a specific type of exclusion clause because its primary purpose is to exclude a party's liability for non-performance when such specified events occur. It defines the circumstances under which a failure to perform will not be considered a breach of contract, thereby excluding the associated legal and financial liability.

A. Indemnity clause: This clause requires one party to compensate the other for specific losses or damages; it does not excuse performance.

B. Liquidated damage clause: This pre-agrees the financial compensation payable in the event of a breach, rather than excusing the breach itself.

C. Insurance clause: This mandates that a party maintains insurance to cover potential risks, a financial protection mechanism, not a relief from contractual duties.

Force Majeure is discussed as a key contractual term for risk management. It is functionally related to exclusion and limitation clauses as it serves to define the boundaries of a party's liability for non-performance. It operates to exclude liability for what would otherwise be a breach of contract. (Refer to sections on 'Key clauses in commercial agreements' and 'Managing contractual risk').

are inserted to "qualify the rights and obligations" of the parties

often by excluding liability in specified circumstances (Section 15-001).
