(a) ELISA

(b) MRI

(c) Ultrasound

(d) WIDAL

Solution : Correct option : A ELISA or enzyme-linked immunosorbent assay is plate based technique. It was the first screening test commonly employed for HIV. It has high sensitivity. The common principle of ELISA is the use of enzyme conjugates that bind to specific HIV antibody and substrates/chromogens, that produces color in a reaction catalyzed by the bound enzyme-conjugate. So, the correct answer is ‘ELISA’
