How Does Immunofluorescence Microscopy Detect Rabies in Brain Tissue of an Infected

How does immunofluorescence microscopy detect rabies in brain tissue of an infected animal?

A) Fluorescent- tagged antibodies bind to rabies antigen in the tissue and are visible in a specialized microscope.
B) Rabies virus naturally fluoresces under ultraviolet light.
C) Fluorescent- tagged antibodies bind to the antibodies generated to fight the infection.
D) Fluorescent- tagged antibodies bind to cytotoxic T cells that are attempting to kill infected cells in the tissue.
E) Fluorescent- tagged antibodies provide light needed to see the virus particles in the microscope.
