Solution

The correct option is A PCR
PCR: Polymerase Chain Reaction is a technique that can amplify a target DNA segment. This amplified segment aids in the detection of various genetic disorder and further studies.
Gel Electrophoresis: It is a method used for separation of macro molecules (DNA, RNA, Proteins) on the basis of their charge:mass ratio.
Chromatography: It is a separation technique that uses stationary phase and mobile phase to isolate pure compound/s from a mixture.
Spectroscopy: It is the study of the interaction of light with matter. For example absorption or emission of light and other radiations by mass. Spectroscopy can be used to identify the structure or functional groups of organic compounds. So, the correct answer is option A
