Solution

The correct options are
A PCR
B ELISA
D DNA Microarray
PCR, ELISA and DNA Microarray are three molecular diagnostic methods. They are called so due to the level of sophistication involved in the diagnostic process. Molecular diagnostic tools involve DNA or RNA fragments or Antigen-Antibody interactions. This makes them highly sensitive and the level of accuracy is high. They aslo rely on molecular interactions like DNA-probe interactions or antibody-antigen interactions.
