The way that vaccination works is by​

A) ​introducing a stronger form of the body's natural defenses.
B) ​introducing a diluted version of the target microorganism.
C) ​introducing a medication that kills a target microorganism.
D) ​introducing a group of antibodies the body cannot produce.

Vaccination works by introducing a weakened or killed form of the target microorganism or a part of it, such as its antigens, into the body. This allows the immune system to recognize and respond to the microorganism if it encounters it in the future, without causing disease. By creating this acquired immunity, vaccination helps prevent infections and protects individuals and populations from outbreaks and epidemics. Introducing a stronger form of the body's natural defenses or a group of antibodies that the body cannot produce is not how vaccination works, and introducing a medication that kills a target microorganism is more similar to treatment than prevention.
