Explanation:

Question 8

Bacterial infections often result in pus formation as the body's immune response to fight the infection. Lesions are not specific to bacterial infections, tissue is normal body structure, and blood presence isn't a specific sign of bacterial infection.

MRSA commonly starts as a skin infection, often appearing as a boil or sore. It's not initially a respiratory, gastrointestinal, or systemic infection.

A communicable disease is one that can be transmitted from person to person. Characteristic refers to a feature, communal relates to a group, and microbial refers to microbes, not transmission.

Answer:

c. pus
