Question
An evil thief has been stealing moped scooters from Cowtown. The 'Scooter Bandit' has successfully stolen seventeen scooters from local citizens in a period of two months, leaving residents cowering in fear. One fateful night the thief takes Detective Willoughby's 'Kaihatsu Raging Pink Zebra 77CX', and while committing the crime, accidentally cuts himself. Despite his escape, Detective Willoughby is able to recover blood evidence. However, it doesn't seem like it will be enough to use for identification.

The best option for Detective Willoughby to obtain enough DNA from the blood evidence is:
**D: polymerase chain reaction (PCR)**
PCR is a technique used to amplify small amounts of DNA, making it possible to generate enough material for analysis, such as DNA fingerprinting or other identification methods. This is particularly useful when the initial sample is limited, as in the case with the blood left behind by the thief.
