Select the correct statement about the function of antibodies. 1) The most potent agglutinating agent is IgG. 2) Complement fixation is the main mechanism by which antibodies provide protection. 3) Antibodies may directly destroy 'invaders.' 4) Neutralization is the process by which antibodies cause invading cells to clump together.
