**Question 20: Which of the following is associated with passive immunity?**A) Exposure to an antigen B) Passage of antibodies from a nursing mother to her baby C) Infusion of weakened viruses D) Booster shot of vaccine E) All of the above *The correct answer is B) Passage of antibodies from a nursing mother to her baby.***Explanation:** Passive immunity refers to the acquisition of antibodies from an external source, rather than through the immune system's own response. This often occurs naturally through maternal antibodies passing to a baby through breastfeeding. Other options involve active immunity, where the body actively produces an immune response.

Immune system is the body's defense mechanism against infection causing foreign organisms or germs…
