Best answer
Correct option is (d) Conjugation

Explanation: Infection is the first stage where the viral particle attaches itself to the bacterial coat and starts to inject its genetic material inside of it. Blending is the second stage where the viral coats were removed from the bacterium by the act of “blending”. Centrifugation is the third stage where the viral particles are centrifuged from the bacterium by spinning.
