Solution

The correct option is B ELISA
One approach for making a provisional diagnosis of enteric fever, sometimes known as typhoid fever, is the Widal test. ELISA is an acronym for enzyme-linked immunosorbent assay. Antibodies in the blood are detected using this routine laboratory test. It looks for HIV antigens and antibodies in the blood. When the body's immune system identifies dangerous molecules called antigens, it produces an antibody.
M. tuberculosis infection can be detected by the Mantoux tuberculin skin test (TST) or the TB blood test.
