Question

1. select the statement that accurately describes passive immunity.

a achieved directly through ready - made antibodies.
b inherited from parents.
c acquired through first exposure to the disease.
d achieved through vaccination.

Explanation:

Passive immunity is when an individual receives ready - made antibodies. For example, a baby gets antibodies from the mother's milk. Inheritance (option b) is related to genetic traits, not immunity in the context of passive immunity. Acquiring through first exposure (option c) is active immunity as the body starts to produce its own antibodies. Vaccination (option d) also leads to active immunity as the body is stimulated to produce antibodies.

Answer:

A. Achieved directly through ready - made antibodies.
