Step 1: Recall the concept of plasma therapy.
In plasma therapy, antibodies from the blood plasma of recovered individuals are injected into a patient to provide immediate immunity.
Step 2: Classify the type of immunity.
This immunity is passive because the recipient receives ready-made antibodies rather than producing them through their own immune response.
It is artificial because it is induced by medical intervention, not natural exposure.
Step 3: Conclusion.
Hence, plasma therapy represents artificial passive immunity.
