(B) Innate immunity is a non-specific type of defense that is present at the time of birth. It provides protection against pathogens by preventing their entry into the body or by eliminating them if they enter. It does not involve the production of antibodies by the body (which is a feature of adaptive immunity) nor does it involve the introduction of ready-made antibodies (which is passive immunity). Therefore,the correct description is that it is present from birth.
