Answer:
It would problably be A.
Step-by-step explanation:
Firstly, California did not have any big existing coal deposits. Furthermore, California had slaves but not to the point where they depend on them. Lastly, Mormons would not have been able to settle in California since it was too far of a trek and not in their reach. It is A because Mexico did own roughly half of California at one point as well as most of Texas.
Hope this Helps!
