If a firm offers a written warranty, it 1. shouldn't be "deceptive" or "unfair" per ftc guidelines. 2. may help create a new strategy. 3. all of the above are true. 4. must be labeled either "full" or "limited." 5. must be available to buyers before the sale.
I believe the answer is 'all of the above are true' Written warranty refers to the written agreement beetween buyer and sellers in order to guarantee a certain type of transaction based on specifics situations that may occur in the future. (in most cases, it can only be claimed if the product is broken or need some new parts)
