The correct answer is D
Step-by-step explanation:
D. Manufacturing Jobs
Manufacturing jobs were not a primary reason for people moving out west during the 1800s. The main factors that attracted people to the western regions during that time included the search for gold (A), the availability of free land through initiatives like the Homestead Act (B), and the desire to spread religious beliefs as missionaries (C). The western migration during the 1800s was often associated with the Gold Rush, the expansion of agricultural opportunities, and the pursuit of religious and economic freedoms, but not specifically with manufacturing jobs.
