Question

The foetus receives some antibodies from their mother through the placenta during pregnancy. Choose the correct option that shows the type of immunity developed in the foetus.

• A. Naturally acquired active immunity
• B. Artificially acquired passive immunity
• C. Naturally acquired passive immunity
• D. Artificially acquired active immunity

Hint:

Naturally acquired passive immunity is temporary and obtained via transfer of ready-made antibodies, such as from mother to fetus.

Answer 1

The Correct Option is C

Step 1: Passive immunity is established when antibodies are received from an external source.
Step 2: For a fetus, this involves maternal antibodies passing through the placenta to confer immunity.
Step 3: This process, occurring naturally without medical intervention, is termed naturally acquired passive immunity.
