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

- Naturally acquired active immunity
- Artificially acquired passive immunity
- Naturally acquired passive immunity
- Artificially acquired active immunity
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Passive immunity occurs when antibodies are transferred from another source.
Step 2: In the case of a fetus, maternal antibodies cross the placenta and provide immunity.
Step 3: Since this is naturally occurring (without medical intervention), it is called naturally acquired passive immunity.
