Which of the following terms indicates the absence of a legal agreement?

The term that indicates the absence of a legal agreement is "void." When a contract is considered void, it means that it is not legally enforceable from the moment it is created. This lack of enforceability can arise from several factors, such as the contract being for an illegal purpose or lacking essential elements like mutual consent, lawful object, or capacity to contract. As a result, a void contract is treated as though it never existed in the eyes of the law.

Other terms, while related, carry different meanings. "Voidable" refers to a contract that may be invalidated by one party due to certain circumstances, but it remains valid until one party opts to cancel it. "Incomplete" suggests that the contract is missing some elements but may still hold legal weight if those elements can be fulfilled. "Invalid" indicates that a contract cannot be executed or enforced, but it does not have the same definitive status as "void," which denotes that there was never a valid agreement to begin with.
