Kim and Jordan Are Both Eyewitnesses to a Bank Robbery

Kim and Jordan are both eyewitnesses to a bank robbery. At the police station they each select Mike from a police lineup, and say, "He's the thief." It turns out though, that Mike has been a customer at the store where Kim works. Jordan has never seen Mike before. With this background, whose identification of Mike is more valuable to the police?

A) Jordan's because Kim may have been misled by the fact that Mike seemed familiar based on her other encounters with him
B) Kim's because she had an advantage of seeing many people come in and out of the store and she is accustomed to identifying faces
C) Both because memory for faces is not distortable
D) Kim's because her recognition of Mike is more powerful due to the previous encounters with him
