The correct answer is Option C: Both Statement I and Statement II are correct.

Let's break down why each statement is true:

Statement I: Antibiotics are chemicals produced by microbes that kill other microbes.

This statement is accurate. Antibiotics are naturally occurring substances produced by certain microorganisms, such as bacteria and fungi. These substances have the ability to inhibit the growth or kill other microorganisms, particularly bacteria.

Statement II: Antibodies are chemicals formed in the body that eliminate microbes.

This statement is also correct. Antibodies are specialized proteins produced by the immune system in response to the presence of foreign substances, such as bacteria, viruses, and toxins. These antibodies bind to specific antigens (markers) on the surface of the microbes, marking them for destruction by other immune cells.

In summary, both antibiotics and antibodies play critical roles in combating microbial infections, but they operate through different mechanisms. Antibiotics are produced by microbes and directly kill or inhibit the growth of other microbes, while antibodies are produced by the body's immune system and specifically target and neutralize microbes.
