Answer:
Yes, because the statement was false.
Step-by-step explanation:
Breach of warranty is defined as a misrepresentation of the quality or type of a product. The seller fails to fulfil a promise or claim made during a transaction.
When a good is being sold there are certain assertions which the seller must stand behind.
In this scenario Mark tells Leslie that his stereo has quadraphonic speakers because he was told that when he bought it.
The fact that the stereo did not have quadrophinic speakers should have been discovered and stated by Mark. The misinformation he got when buying the stereo does not clear him of breach of warranty
