Why is a cell-mediated immune response more effective against intracellular microorganisms (such as viruses) than an antibody-mediated response?

A. Cell-mediated response results in destruction of cells containing the intracellular microorganism; antibodies can not enter cells.
B. Cell-mediated (vs. antibody-mediated) response results in activation of many more immune cells, so it is more effective at destroying antigens.
C. Intracellular microorganisms are too large for antibodies to be effective against.
D. Intracellular microorganisms are too small for antibodies to be effective against.
