Final answer:
A contract created by actions is known as an Implied Contract (Answer A). It's based on the actions or circumstances of the parties involved, unlike express, unilateral, or executed contracts, which have different defining features.
Step-by-step explanation:
A contract created by actions rather than oral or written words is called a(n) Implied Contract. The correct answer to this question is A) Implied Contract. An implied contract is formed by the actions, behaviors, or circumstances of the parties involved, rather than through their verbal or written agreement. For example, if you visit a doctor for a check-up, even without explicitly agreeing to pay in advance, it's assumed that you have entered into an implied contract to pay for the medical services provided.
On the other hand, an express contract is based on a written or spoken agreement, while a unilateral contract involves a promise in exchange for a specific act, and an executed contract is one where all parties have fulfilled their obligations.
