In a prosecution of Dahle for assault, Wharton is called to testify that the victim, Valerian, had complained to Wharton that Dahle was the assailant. Wharton's testimony is most likely to be admitted if Wharton is 
a doctor, whom Valerian consulted for treatment.  a minister, whom Valerian consulted for counseling.  Valerian's husband, whom she telephoned immediately after the event.  a police officer, whom Valerian called on instructions from her husband.
