Mary Was Selling Her House

Mary was selling her house. The purchase asked if it had termites and Mary replied in horror, "absolutely not". However, it did have termites.

A) an innocent misrepresentation
B) a negligent misrepresentation
C) a false warranty
D) of no consequence because it was not included in the written contract
E) of no consequence because she believed that there were no termites and was honestly mistaken
