A land appraiser prepared an appraisal of a property for a real estate development company. The appraiser had been told that the appraisal would be used by the company to attract potential investors. Because the appraiser forgot to check the recent changes in the zoning by-laws, the appraisal was not accurate and the investor, a party unknown to the appraiser, was misled about the value of the land and consequently, suffered a financial loss. On these facts, which of the following is true? Select one: O a. The investor must suffer his own loss, because an investor takes the risk and so must take care. O b. A land appraiser owes a duty of care to his client, the company, but not to any potential investors. c. A person cannot be sued for words that cause loss, only for actions that cause physical injury. d. The cause of action that could be taken by the investor is "negligent misstatement causing economic loss."
