A) The classical pathway is initiated by the binding of antibodies to the pathogen's surface.
B) The alternative pathway can be activated spontaneously when certain proteins interact with foreign surfaces.
C) The lectin pathway is activated by the binding of lectins to carbohydrates on the pathogen's surface.
