A material supplier begins deliveries without tracking the participants or deadline needed for its preliminary notice. Which future rights may be endangered?

Why B is correct

The best answer is: It may preserve payment remedies. California remedies contain strict claimant, recipient, content, and timing rules. The notice alerts key parties and preserves rights; it does not prove the debt or eliminate other prerequisites. The new fact pattern changes the setting, not the governing rule or management control. The other choices either skip a required step, apply a different rule, or fail to address the stated risk.
