PLEASE HELP In what way did mountain men and trappers prepare the West for settlement?

b they killed most of the dangerous animals
c they fought off most lf the hostile indian tribes
d they mapped trails and helped build forts

D. They mapped trails and helped build forts

Explanation:

I would say D. They mapped trails and helped build forts.

The trails they used were used later by many settlers to travel out West and many became extremely famous, like the Oregon Trail.
