Final answer:
Mark is liable if he stood to benefit from the misrepresentation.
Step-by-step explanation:
The correct answer is D) Mark is liable if he stood to benefit from the misrepresentation. In the scenario described, Mark is a sales agent representing the seller. Under the principle of agency law, Mark is considered the seller's representative, and any misrepresentations made by the seller can be attributed to Mark. If Mark stood to benefit from the misrepresentation, such as earning a commission on the sale, he can be held liable for statutory fraud.
