Answer:
The correct answer is a requirements contract.
Step-by-step explanation:
Contract requirements are those essential for a contract to simply be born into legal life, regardless of whether or not it does so with validity or effectiveness. Therefore, they refer to a mere question of fact that could respond to the question: is there a contract? Such requirements are: the expression of will, the existence of an object and a cause. Once these three requirements are met, the previous question can be answered affirmatively. Otherwise there is no contract, the event has not occurred. As the Civil Code does not contain norms related to this question of existence, the courts generally sanction the omission of any of the indicated requirements declaring the contract null.
