Jack Was on Trial for the Murder of Kim's Husband

Jack was on trial for the murder of Kim's husband. Kim, who was present when her husband was shot, testified at the trial: Prosecutor: Were you present when your husband was shot? Kim: Yes, I was about three feet from him. I'll never forget it. Prosecutor: Do you think you can identify the person who shot your husband? Kim: Yes, he's sitting over there, at the table with the sign that says Defense. Prosecutor: Are you positive? Now I know you picked him out of a lineup, but the judge has ruled that the lineup was not conducted properly. So I just want to make sure you are not thinking about the lineup. Kim: Oh, I know it's him. At the lineup I looked at his face and I was sure he was the man I saw shoot my husband. But I just noticed that tattoo on his neck. I've never seen a tattoo like that except the one on the man who was shooting my husband. So I'm sure it was him. Can Jack's defense attorney call a psychologist as an expert witness to testify about the fallacy of eye-witness identifications?

A) Yes, but only if the psychologist has treated Kim for post-traumatic stress disorder.
B) Yes, a psychologist who has studied problems with perceptions, memory, and the emotional state of witnesses can testify about possible errors made when identifying a suspect.
C) No, a psychologist would be allowed to testify only if he or she provided counseling for Kim immediately after her husband's death.
D) No, the defense can cross examine Kim but it is not allowed to call a psychologist to cast doubt on her testimony.
