Option A and C

In quasi-contract cases, the defendant received a benefit from the plaintiff. In promissory estoppel cases, the defendant made a promise that the plaintiff relied on.

A quasi-contract is a retroactive system among two parties who own no prior commitments to one another. It is designed by an expert to change a situation in which one individual takes something at the value of the other. The plaintiff must have provided a substantial thing or service to the added party with the expectation or assumption that mortgage would be supplied.

Promissory estoppel is a concept in contract law that hinders a character from performing reverse on a commitment even if a legitimate contract does not endure.
