contract valued at $18,000 for kitchen remodeling work. The
contractor begins work without including a statutory notice regarding
the owner’s right to cancel within three business days, fails to provide
a schedule of progress payments, and neglects to include the
contractor’s license number on the first page of the contract. Under
California contractor law, which of the following statements best

A. The contract automatically becomes void and the contractor forfeits all

and may subject the contractor to disciplinary action and civil penalties

satisfies all statutory requirements

B. The omissions constitute violations of the Contractors State License Law
and may subject the contractor to disciplinary action and civil penalties
Rationale: California law requires specific disclosures in home
improvement contracts, including cancellation rights, payment schedules,
and the contractor’s license number. Failure to comply may expose the
contractor to administrative discipline, fines, and disputes regarding
enforceability, although the contract is not automatically void in every
circumstance.

most directly implicated by this conduct?
A. Implied warranty of merchantability
