Solution

The correct option is A Certain types of bacteria
Lysozyme is an antimicrobial enzyme produced by animals that form part of the innate immune system. Lysozyme is abundant in secretions including tears, sweat (perspiration), saliva, human milk, and mucus. The action of lysozyme is physiological as it is an antimicrobial enzyme which kills certain types of bacteria. The enzyme functions by attacking, hydrolyzing, and breaking glycosidic bonds in peptidoglycan (cell wall) of bacteria.
So, the correct answer is 'Certain types of bacteria'.

Ampicillin-resistant bacterial population (Strain 1) is grown in a laboratory is infected with a virus. The virus initially goes through the lytic cycle and thus bacterial population begins to decline, then rebounds as the virus integrates
into the bacterial chromosome to begin the lysogenic cycle. The bacteria reproduce normally until they are heat-shocked. The virus removes itself from the bacterial genome and enter the lytic cycle because of the temperature is increasing rapidly. Within several hours all bacteria are dead and a free virus is found in high concentration in the bacterial growth medium. This free virus infects bacterial population that is sensitive to ampicillin (Strain 2). After the expected decrease and rebound of this bacterial population (as above), the rebounded population was found to be ampicillin-resistant. Oxygen is constantly infusing in bacterial culture to ensure a high rate of reproduction among the bacteria and a health.
