What your opposing legal counsel is expecting.....
Most counsels are expecting the origin and cause expert, or any fire expert, to use #4, "A rapid oxidation process, which is an exothermic chemical reaction, resulting in the evolution of light and heat in varying intensities." This is the definition from NFPA 921.
