Final Answer:
The major immunologic defense mechanisms against bacteria include Lysozyme (A) and Phagocytosis (B).
OpyiOption D. is the correct answer.
Step-by-step explanation:
A. Lysozyme is an enzyme that breaks down bacterial cell walls, disrupting their structure and rendering them more susceptible to other immune defenses.
B. Phagocytosis is a process where immune cells, such as macrophages and neutrophils, engulf and digest bacteria. These cells recognize, engulf, and destroy pathogens as part of the innate immune response.
C. Interferon production is a defense mechanism against viruses, not bacteria. Interferons are proteins that inhibit viral replication and spread.
D. Option "Both A and B" is accurate, as both Lysozyme and Phagocytosis are crucial components of the immune system's defense against bacterial infections.
Option D is answer.
