Answer :
1. This is known as the classical activation pathway. Option 4. 2. The granulocytes include basophils, eosinophils, and neutrophils. Option 3.
1. When the complement protein, C1q, is activated by an antibody that the body has produced in response to a microbe such as bacteria, this initiates a sequence of events resulting in the generation of Membrane Attack Complexes (MAC) that lyses or breaks down, the microbe.
This process is known as the classical activation pathway, not the inflammatory pathway. Therefore, the correct answer is Option 4.
2. Meanwhile, basophils, eosinophils, and neutrophils are types of granulocytes, not monocytes. These different types of cells play crucial roles in the body's immune response to infections.
Therefore, the correct answer is Option 3. granulocytes.
