Traffic in Major Metropolitan Areas Is Too Often Brought to a Standstill

Traffic in major metropolitan areas is too often brought to a standstill after wreckage has been cleared away because investigators must painstakingly measure skid marks and determine culpability.After a police chief missed an important meeting because of a wreck investigation,he was pleased to find an article about a company that markets a new high- tech crash investigation system that shortens the time required for these investigations by 50 percent.In which stage of the adoption process is the police chief?

A) adoption,when it purchased the system,because he is buying the product
B) confirmation,because he is convinced the city made the right decision
C) evaluation,because he is looking for similar products
D) trial,because he is testing the effectiveness of the system
