Verified step by step guidance

Understand the concept of passive immunity: Passive immunity involves the transfer of antibodies from one individual to another, providing immediate protection without the recipient's immune system actively producing these antibodies.

Identify the examples provided: The options include transfer of antibodies from mother to child through breast milk, production of antibodies by B-cells, activation of T-cells by an antigen, and vaccination with a live attenuated virus.

Analyze each option: Consider which options involve the direct transfer of antibodies rather than the body's active immune response.

Focus on the transfer of antibodies: Passive immunity is characterized by the direct transfer of antibodies, such as through breast milk, which provides the child with immediate protection.

Conclude which option represents passive immunity: The transfer of antibodies from mother to child through breast milk is a classic example of passive immunity, as it involves the direct transfer of antibodies without the child's immune system actively producing them.
