In which of the following circumstances, the quasi contractual obligations arise?

There are a number of different types of quasi-contractual obligations, including:

• Liability of a finder of goods: A finder of goods is liable to the owner of the goods if they fail to take reasonable steps to return them.
• Compensation for non-gratuitous acts: A person who performs a non-gratuitous act (i.e., an act that is not done as a gift) may be entitled to compensation if the other party benefits from the act.
• Recovery of payments made by interested persons: A person who makes a payment to another person on behalf of a third party may be able to recover the payment if the third party does not reimburse them.

Quasi-contractual obligations are enforced through the courts. If you believe that you have been unjustly enriched at the expense of another, you may be able to file a lawsuit to recover the enrichment.
