Answer: (A)

Verified step by step guidance

1. Understand the concept of bacterial pathogenesis, which involves the process by which bacteria cause disease in a host.
2. Identify the typical phases of bacterial pathogenesis: transmission, colonization, invasion, and multiplication within the host.
3. Recognize that the destruction of bacterial pathogens by neutrophils and macrophages is part of the host's immune response, not a phase of pathogenesis.
4. Differentiate between the phases of pathogenesis and the immune system's response to bacterial infection.
5. Conclude that the destruction of bacterial pathogens by the immune system is not a phase of bacterial pathogenesis.
