Identify the wrong statement with reference to immunity.

1. When exposed to antigen (living or dead) antibodies are produced in the host's body. It is called "Active immunity".

2. When ready-made antibodies are directly given, it is called "Passive immunity".

3. Active immunity is quick and gives full response.

4. Foetus receives some antibodies from mother, it is an example for passive immunity.

Best answer

Answer: 3. Active immunity is quick and gives full response.

Key idea: Active immunity is slow; passive immunity is quick.

In active immunity the host makes its own antibodies after exposure to antigens (living or dead), which takes time to develop a full response. Statement 3 is wrong. Statements 1, 2 and 4 are correct.
