Statement II: Antibodies are chemicals formed in body that eliminate microbes.
In the light of the above statements, choose the most appropriate answer from the options given below.

A

Statement I is correct but Statement II is incorrect

B

Statement I is incorrect but Statement II is correct

C

Both Statement I and Statement II are correct

D

Both Statement I and Statement II are incorrect

Answer

Both Statement I and Statement II are correct

Explanation

Solution

Statement I: Antibiotics are indeed chemical substances produced by certain microorganisms (like bacteria and fungi) that can inhibit the growth of or kill other microbes. This statement is correct.

Statement II: Antibodies are produced by the immune system (specifically by plasma cells) that recognize and neutralize foreign substances, including microbes. While antibodies don’t directly kill microbes, they mark them for destruction by other immune cells or neutralize them through their toxic effects. Therefore, the statement “Antibodies are chemicals formed in the body that eliminate microbes” is a slightly simplified but generally correct description of their function. Thus, this statement is also correct.
