Art Historian: Recently, computer analysis has revealed that a few of a famous Flemish artist's works are forgeries, and are actually the work of noted forger Elmyr de Hory. While such a development may emit violent reverberations through the art world, even those museums that have a wealth of the Flemish artists in their collections should not be overly concerned. Hundreds of this Flemish artist's works were tested to determine whether they were forgeries, yet only a slim few turned out to be actual forgeries. Thus, the master's reputation as one of the greatest artists humanity has ever produced will surely remain undiminished. Which of the following, if true, casts the most doubt on the art historian's conclusion? ["Some of the works upon which the Flemish artist's standing rests were identified by the computer analysis to be the work of de Hory.", "Though few in the art world dispute the outcome of the computer analysis of the Flemish artist's work, many contend that the identified forgeries are not the work of Elmyr de Hory but some other highly skilled forger.", 'The computer analysis involved is more likely to mistake an actual work as a forgery than to mistake a forgery as an actual work.', "Many of the Flemish artist's well-known portraits are in the collection of private owners and were ttherefore not subjected to computer analysis."]
