A man was prosecuted for the false imprisonment of a woman after he allegedly pretended to have a broken arm, asked the woman to help him carry a box into the back of his van, and then pushed her into the van and locked it. At trial, the prosecution attempted to introduce evidence during a female witness’s direct examination that five years ago, the man had impersonated a policeman, entered the witness’s home, and made serious threats of harm if the witness did not stay in the home and answer his questions.

Is this evidence admissible?

a. Yes, because it shows that the man has the propensity to falsely imprison women.
b. Yes, because it is relevant evidence that shows the man's preparation and planning.
c. No, because it is improper character evidence.
d. No, because it can only be introduced during cross-examination.
