CFDRS characteristics include how many fuel models?

Explanation:
CFDRS relies on a fixed set of standard fuel descriptions to drive fire behavior calculations. Each fuel model represents a group of fuels with specific characteristics (like load, how they burn, and how quickly they transfer heat) so the system can estimate spread, flame length, and intensity consistently across different landscapes. The standard CFDRS library includes sixteen fuel models, which provides enough variety to cover common fuel types while keeping the toolkit practical for field use. That’s why sixteen is the best answer here. The other counts don’t match the established CFDRS library, which is why they aren’t correct.
