Fred argued that, since Kathlees is a successful film

Fred argued that, since Kathlees is a successful film director, she has probably worked with famous actors. But, while Fred is right in supposing that most successful film directors work with famous actors, his conclusion is not warranted. For, as he knows, Kathlees works only on documentary films, and directors of documentaries rarely work with famous actors.

Which one of the following strategies is used above to criticize Fred's reasoning?

A. maintaining that too little is known about Kathleen to justify any
conclusion

B. showing that Kathleen must not have worked with famous actors

C. claiming that Fred has failed to take relevant information into account

D. showing that Fred has mistakenly assumed that all successful film directors work with famous actors

E. demonstrating that Fred has failed to show that most successful film directors work with famous actors
