Answer:

B - by comparing DNA from the blood cells with DNA from suspects!

Explanation:

DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation.

<em>A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. </em>

If the two DNA profiles are a match, then the evidence came from that suspect. (from www.genome.gov )

Hope this helps! :]
