Which of these most nearly define caveat emptor?

Caveat emptor is Latin for "Let the buyer beware." It means that in a contract matter where one person is buying something from another person, the buyer has the responsibility to make sure what he is buying is in good shape. Once he takes delivery and the money changes hands, the buyer can't complain that the item purchased is not good, unless there has been some fraud or deception by the seller. This is why when buying houses, a buyer, does a title search, a survey a home inspection and things like that. The buyer has to be sure there are no problems with what he is buying.
