Solution
The correct option is A increased
Polymerase chain reaction is a technique used to amplify the quantity of DNA isolated from a sample. PCR can make numerous copies of DNA in a small amount of time with a considerable precision. This increases the sensitivity of DNA fingerprinting considerably. Sensitivity implies that PCR can be used to amplify DNA which may only be present in trace amounts in a sample.
