    Answer choice B may be a necessary assumption but it is not sufficient to prove the case. The beginning states that whoever committed the murder was in the office on the day of the crime. Remember that a sufficient assumption is an extra premise that, when added to the existing information proves the conclusion. Therefore, since Janson's killer had to be in the office and Herbert is ruled out, it proves that Samantha did it if no one else were in the office that day.
