Correct answer

B. ( a ) - ( ii ) ,   ( b ) - ( i ) ,   ( c ) - ( iv ) ,   ( d ) - ( iii )

Step-by-step solution

Techniques/Instruments Usage Bioreactor It is used for the large scale production of desired products Electrophoresis Separation of DNA fragments based on molecular size. Large fragments are found near the cathode, while smaller fragments are found near the anode. PCR It is also called amplifier as it is responsible for Amplification of nucleic acids. ELISA Detection of the pathogen, based on antigen-antibody reaction. It is one of the confirmatory tests for detection of HIV .
