Answer:
(D). an implied contract.
Step-by-step explanation:
An implied contract is one that is assumed to exist, based on the actions carried out by the parties involved or on the circumstances surrounding the occurrence.
Such a contract can be enforced even in the absence of a verbal or written agreement.
In this case, there is an implied contract between Jeff and Kwik Tow Inc. even if no agreement on a price was discussed earlier.
