Keshon and Robin have a claim to the same collateral: Lachelle's car. Keshon's security interest is perfected, but Robin's is not. The debt Lachelle owes to Keshon is $$4,000,$ and the debt Lachelle owes to Robin is $$3,000.$ Lachelle owed the debt to Robin first. Whose security interest has priority?

Robin's, because Lachelle owed the debt to Robin first.

Keshon's, because when two or more parties have claims to the same collateral, a perfected secured party's interest has priority over the interests of most other parties.

Keshon's, because the debt to Keshon is greater than the debt owed to Robin.

Neither, because security interests are treated equally.
