Solution

The correct option is A Assertion(A) is true and reason(R) is false.
Correct answer: (c) Assertion(A) is true and reason(R) is false.

$∙$ The lymphocytes are the cells that determine the specificity of the immune response to infectious microorganisms and other foreign substances.
$∙$ Damaged lymphocytes are unable to produce antibodies against the antigens.
$∙$ This decreases the immune response of our body.
$∙$ Injection of dead pathogens (inactive vaccines) provide artificially acquired active immunity.
$∙$ So, the assertion is true, but the reason is false.
