Answer & explanation
Correct answer: option 1

Passive immunity refers to the administration of pre-formed antibodies directly into the body to provide protection against foreign agents.

Additionally, during pregnancy, the fetus acquires a certain amount of antibodies from the mother through the placenta. These instances illustrate examples of passive immunity.
