Which of the following contracts indicates duties and obligations through actions rather than words?

The correct answer, implied contract, refers to agreements where the responsibilities and obligations are established through actions and behavior rather than through explicit verbal or written communication. This type of contract exists when the conduct of the parties involved suggests that they have reached an understanding, even if no formal agreement has been articulated.

For instance, when a person sits down at a restaurant to eat and orders food, there is an implied contract that they will pay for the meal, even though no spoken agreement has taken place. The actions—placing an order and receiving a meal—indicate mutual consent to the terms of service.

In contrast, an express contract is one where the terms are clearly defined by the parties involved verbally or in writing, which is fundamentally different from relying on actions alone. A unilateral contract involves a promise made by one party in exchange for an act from another party, such as a reward for finding a lost pet, but again, this differs from the mutual understanding conveyed through actions. A joint contract typically refers to an agreement made by two or more parties where all parties are equally responsible, which does not specifically relate to the manner of conveying duties through actions. Thus, the key characteristic of an implied contract is that it forms based on actions rather than explicit statements,
