Long and difficult journey is the option that best describes life along the Oregon Trail. So, option B is correct.
The Oregon Trail is the central feature of one of the largest mass migrations of people in American history. Between 1840 and 1860, from 300,000 to 400,000 travelers took the 2,000-mile overland route to reach Willamette Valley. The journey took up to six months, with wagons traveling between ten and twenty miles per day of travel.
