Solution

The correct option is B if both Assertion and Reason are true but Reason is not the correct explanation of Assertion
When antibodies produced in one body (human or animal) are transferred to another to induce protection against disease, it is known as passive immunity, In other words, the body does not produce its own antibodies but depends upon ready-made antibodies. Passive immunity differs from active immunity in the following respects :
(a) immunity is rapidly established
(b) immunity produced is only temporary (days to months) till the antibody is eliminated from the body.
So, the correct answer is 'if both Assertion and Reason are true but Reason is not the correct explanation of Assertion'.
