What is the end result of using a technique known as polymerase chain reaction
is it B, C, OR D???

The answer is C; Many copies of a DNA Fragment

The specific DNA sequence has been doubled. This cycle of Denature-Anneal-Extend is repeated, usually about 35 times, by using a thermocycler over 2-3 hours (the "chain reaction" of PCR). This produces 34,359,738,368 copies of DNA (That's 2^35)!
