1. The defect giving rise to the purchaser's option for defect is the latent defect. 2. A defect is latent if it is old and existed in the subject matter of the sale before the sale, or arose thereafter while in the seller's possession and before delivery, and is of a kind that cannot be detected by ordinary inspection, is not apparent to an ordinary person, can only be discovered by an expert, or only appears through testing. 3. Any defect that appears after the purchaser has taken delivery of the subject matter of the sale shall likewise be deemed a latent defect if it is proven to have arisen from a cause existing in the subject matter of the sale before delivery.
