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.

Options

• Naturally acquired active immunity

• Artificially acquired passive immunity

• Naturally acquired passive immunity

• Artificially acquired active immunity

Answer 1

Naturally acquired passive immunity

Explanation:

During pregnancy, the placenta transfers antibodies (IgG) from the mother to the fetus. Without the fetus producing its own immune response, this offers transient immunity. Because immunity does not involve the creation of memory cells, it is spontaneously transmitted in the form of premade antibodies. As a result, passive immunity is spontaneously acquired.
