Answer:
a, behavioral sketch
Step-by-step explanation:
not only did I take this exam, but the question emphasizes "possible psychological clues" and talks of what the crimes have in common. This would led to the answer being phycology related.
b, physical sketch is incorrect since this refers to a physical drawing which cannot express/draw psychological concepts.
c, criminal hypothesis is wrong, because not only has that never been a idea/concept/term taught but hypothesis is a step of the scientific method which is a module 9 concept, not a module 12 one.
d, pneumography is wrong since it is pneumographs are two rubber tubes filled with air that measure one's respiratory rate.
