    Passive immunity is when you get antibodies from someone else- either naturally (across the placenta or in breast milk) or artificially (through an injection of immune globulin)- as opposed to making your own antibodies in response to infection or immunization. So the answer is A.

    i'm no healthcare expert yet i want to declare D because of the fact that's the only one that openly seems diverse. The others contain issues that are rapidly in touch in immunity at the same time as D is something that finally ends up in the form of issues like that and consequentially is circuitously in touch.
