D. the weakened viruses are too weak to cause illness.

Answer 1

I believe the correct response would be C. Production of antibodies.

Answer 2

The correct answer would be C. the weakened viruses promote the production of antibodies.

The administration of a weakened or attenuated microorganism or antigen is termed as vaccination.

It leads to the production of a primary immune response by which body's B cells produce antibodies and memory cells.

In later life, whenever the body is encountered with same microorganism or antigen, the memory cells are capable of recognizing it which leads to the generation of the quicker and high-intensity immune response.

Consequently, our immune system could easily defeat the pathogen and prevent the occurrence of the disease.
