Overview

Explanation

The correct answer is C. IgG is the main type of antibody found in blood and extracellular fluid, allowing it to control infection. The most abundant type of antibody is the IgG and is found in all body fluids. It protects against bacterial and viral infections but does not directly attack invaders such as viruses and bacteria, activate inflammation, or the kinin system.
