Final Answer:
The seller is not liable because the buyer should not have incurred the $1,500 cost before the sale. Option B is the answer.
Step-by-step explanation:
In a business transaction, it is generally the buyer's responsibility to be aware of the terms and conditions. If the buyer incurred a cost of $1,500 before the sale without proper agreement or authorization, the seller is not typically liable for that expense. Buyers should exercise due diligence and follow agreed-upon procedures to avoid incurring costs that are not the responsibility of the seller. The principle of prudence and clear contractual terms helps establish liability in such situations.
Option B is the answer.
