Firefighters should practice ___ in order to be warned of extreme fire behavior or structural collapse

A view factor method:

A) identifies the minimum temperature required for ignition of fuel gases under specific test conditions. B) determines the temperature required to produce the lower flammable limit and can be ignited in the presence of a piloted ignition source. C) determines the temperature at which oxidation reactions will initiate within fuel/air mixtures without an outside pilot source. D) approximates the flame as a geometric shape and uses an average emissive power of the geometric object to estimate the heat flux to a target.
