• A. Anaerobic bacteria
• B. Aerobic bacteria
• C. Fungi
• D. Protozoa

Answer 1

The correct option is A Anaerobic bacteria

A person applies hydrogen peroxide on his wound. This is to kill anaerobic bacteria. Anaerobic bacteria cannot survive in the presence of oxygen. The hydrogen peroxide bubbling releases oxygen. Hence, due to the released oxygen, anaerobic bacteria will be killed. However, it also affects the healthy cells of the body. This in turn slows down the process of wound healing.

Thus, the correct answer is 'Anaerobic bacteria.'
