Which of the following challenges did travelers on the oregon trail often face in the mid-1800s? a. traveling across the desert b. crossing the great plains c. dealing with apache attacks d. being exposed to the harsh sun

I believe the answer is:B. crossing the Great Plains

The great plains typically had low water resources, high temperature, and very little animals and vegetations that can be used as food. Crossing The great plains would require high amount of supplies that can be really expensive for the travelers along with high security to protect them from being robbed in the middle of the roads.
