Assertion (A): | Some human organs like liver, kidney fail to function normally and transplantation is the only remedy to enable the patient to live a normal life. |
Reason (R): | Tissue matching and blood group matching are essential before undertaking any transplant and patient has to take immunosuppresant thereafter. |

Identify the wrong statement with a reference to immunity.
1. | When ready-made antibodies are directly given, it is called “Passive immunity". |
2. | Active immunity is quick and gives a full response. |
3. | Foetus receives some antibodies from the mother, it is an example of passive immunity |
4. | When exposed to antigen(living or dead) antibodies are produced in the host's body. It is called "Active immunity |
