Question

Which of the following natural immunity matches is incorrect?​

Answer 1

Answer:

Explanation:

A) Natural active immunity is immunity that is inborn or present from birth. Fighting infections naturally is natural active immunity. So, 's' is correct for 'A''. Vaccination is artificial active immunity. So, 't' is wrong for 'B'.

B) Vaccination is artificial active immunity. So, 't' is wrong for 'A'.

C) Immunity is not inherited so statement 'p' is wrong.

D) 's' is correct for 'A'. 'r' is correct for 'B' as antiserum is a method of artificial passive immunity. 't' is correct for 'C' as vaccinations are a form of artificial active immunity. 'q' is correct for 'D' as the immunity (antibodies) acquired from the mother through the placenta is natural passive immunity.

So the correct answer is 'A−s,B−r,C−t,D−q'.
