Dr Ferenz, an Older Male Psychologist, Conducts Extensive Interviews with Rape

Dr. Ferenz, an older male psychologist, conducts extensive interviews with rape victims. From these interviews he finds that the rape victims display little about the traumatic effects of this crime. However, Dr. Martinez, a middle-aged female psychologist, replicates his study and finds a rich portrait of the after-effects of rape. Why would the results of these two studies differ so widely?

A) the two probably asked very different kinds of questions, due to experimenter expectancy
B) the different results are probably due to an experimenter-attribute effect because female rape victims are probably more comfortable disclosing information to a woman than to a man
C) the participants probably figured out what each experimenter wanted to know, and gave them the answers they wanted, a demand characteristic
D) Dr. Martinez was probably "mining" her data for facts that weren't really there, an experimenter-bias effect
